The McKinley High School gang is getting sexy next week as Gwyneth Paltrow returns for her second episode of 'Glee.'

The songs from 'Sexy' were released online today, and they're quite delightful. The big group number this week is an interesting choice: Standard Vocal Band's 'Afternoon Delight.' It's an oldie, sure, but one awesome thing keeps it from boring-ville: STAMOS. Yes, John Stamos' dentist is back on Tuesday's show, where he'll apparently be getting sex advice from Paltrow's Holly Holiday.

Also covered this week: Paltrow does Fleetwood Mac's 'Landslide,' Joan Jett's 'Don't You Wanna Touch Me (Oh Yeah)' and joins the New Directions gang on Prince's 'Kiss,' and the Dalton Academy Warblers go indie with a Kurt and Blaine duet of Neon Trees' 'Animal.'

Listen to all the tunes below.

The latest 'Glee' soundtrack, 'Glee: The Music, Volume 5,' doesn't come out until Tuesday, but our friends at AOL Music are streaming the album in its entirety right now.

You've already heard most of the tracks, which all come from the post–Super Bowl episode and beyond. That means plenty of Michael Jackson (the 'Thriller'/'Heads Will Roll' mashup, 'PYT'), Justin Bieber ('Baby,' 'Somebody to Love'), 'Fat Bottomed Girls,' 'Firework' and 'Sing.'

Conspicuously absent: any trace of the Dalton Academy Warblers beyond Blaine and Rachel's duet of 'Don't You Want Me.' Where's 'Silly Love Song'?!

Read the rest of our thoughts on the album (lots of Gwyneth Paltrow!) after the jump.

It appears Rachel Berry's wish is coming true: New Directions will definitely take on original songs in an upcoming episode of 'Glee.'

The two tunes, 'Loser Like Me' (co-written by the man behind Britney Spears' biggest hits, Max Martin) and 'Get It Right' (a ballad apparently tailor-made for Lea Michele), will debut on 'Glee: The Music, Volume 5' when it's released on March 8 and will be included in the March 15 episode of the show.

Also on the new disc: two Michael Jackson tunes (the buzzed-about 'Thriller'/'Heads Will Roll' mashup and 'P.Y.T. (Pretty Young Thing),' two Justin Bieber tracks ('Baby' and 'Somebody to Love'), the Katy Perry cover 'Firework' and the return of Gwyneth Paltrow on Prince's 'Kiss,' Fleetwood Mac's 'Landslide' and Joan Jett's 'Do You Wanna Touch Me (Oh Yeah).'

Check out the full tracklist after the jump.

The 'Glee' characters are having a booze-fueled party on next week's episode, and you know what that means: alcohol-themed songs!

'Blame It On the Alcohol' also marks an inevitable first for 'Glee': They cover Ke$ha. Yes, just when 'Tik Tok' had finally faded into radio oblivion, 'Glee' is bringing it back. One positive? Heather Morris is the focal point of this performance.

Other songs from the Feb. 22 episode include a Rachel and Blaine duet on the '80s classic 'Don't You Want Me,' Will and Coach Beiste singing 'One Bourbon, One Scotch, One Beer' and Artie taking the lead on Jamie Foxx's 'Blame It.'

What are you waiting for? Get crunked on 'Glee' music below!

We'll ignore the curious bit of synchronicity surrounding the release of Justin Bieber's documentary/biopic/concert movie today and 'Glee's' Bieber episode on Tuesday because OMG! 'Glee' and the Biebs! Together!

'Glee' released the full versions of the songs from next week's non-Justin Bieber-themed episode, 'Comeback.' According to the official synopsis, "Rachel tries to launch a comeback into the McKinley High social stratosphere with a little help from Brittany. Meanwhile, Sam starts a tribute band." Naturally, that involves purple Bieber hoodies for the dudes and Berry-tastic makeovers for the ladies.

After the jump, listen to the 'Glee'-ified Bieber tunes 'Somebody to Love' and 'Baby,' plus covers of 'Rent's' 'Take Me or Leave Me,' My Chemical Romance's 'Sing' and The Waitresses' 'I Know What Boys Like.'

Apparently one epic episode of television per week isn't enough for 'Glee.' Following yesterday's highest-ever-rated telecast after the Super Bowl, the show will return to its regular time slot tomorrow night for the Valentine's Day–themed 'Silly Love Songs.'

In the all-new episode, the McKinley High gang (and a couple of Dalton Academy Warblers) will find themselves in a variety of romantic entanglements. After the jump, listen to this week's tunes and watch a few leaked scenes from tomorrow's episode.

With just six days left until the highly anticipated 'Glee' Super Bowl episode (eeeee!), it's about time the powers that be released some of the music.

Today, PopEater has the exclusive premiere of the 'Thriller' / 'Heads Will Roll' mashup, which combines the Michael Jackson classic with Yeah Yeah Yeahs' 2009 hit. YYYs paid homage to 'Thriller' for their own 'Heads Will Roll' video, so the connection isn't completely out of left field. Plus, both songs feature creepy organ music that the 'Glee' gang turned into a fun, poppy dance beat.

Head over to PopEater for the exclusive premiere of the track, plus details on your chance to win a prize pack that includes four 'Glee' soundtrack volumes and Michael Jackson's 'Vision.'

What's that? You're excited for New Directions to head to sectionals on 'Glee' tomorrow night? Sorry, we couldn't hear you over the constant loop of 'Don't Cry for Me Argentina' and 'Dog Days are Over' we've been playing all day.

Last week we heard Santana tackle 'Valerie,' Sam and Quinn duet on '(I've Had) The Time of My Life,' and Blaine lead the Warblers in an a cappella version of Train's 'Hey Soul Sister.' Today, the rest of the songs from the already jam-packed episode have leaked, including 'Dog Days,' separate Kurt and Rachel versions of 'Don't Cry for Me Argentina' and the Hipsters' cover of 'The Living Years.'

This just in: A news anchor on a major network could soon expand her repertoire to scripted television.

If all goes according to the 'Glee' producers' plan, CBS Evening News anchor Katie Couric could suit up for an appearance during the Fox show's much-hyped post-Super Bowl episode. According to Deadline Hollywood, Couric is "in talks" to cameo in the Feb. 6 episode.

The appearance would reportedly feature Couric in a scene with Jane Lynch. One of the episode's plots involves the Cheerios competing in their regional cheerleading championships.

Tomorrow's episode of 'Glee' is dedicated to the origins of Sue Sylvester and her Nazi-hunting mother, played by Carol Burnett, with a significant side plot dedicated to the nuptials of Kurt's dad and Finn's mom. But it seems the episode is also unofficially dedicated to the oeuvre of Bruno Mars.

Two of the four tracks from 'Furt' are by Mars: the hit single 'Just the Way You Are' and the album cut 'Marry You.' We have just one major question: Which 'Glee' producer is so impressed with Bruno Mars that essentially four of his tracks have been covered this season, which is a mere eight episodes long so far?

Besides the two tracks from tomorrow's show, Mars was featured on the Travie McCoy song 'Billionaire,' which newbie Chord Overstreet covered in the first episode. Plus, Mars co-wrote 'F*** You,' the Cee Lo Green song covered by Gwyneth Paltrow in its radio-friendly form ('Forget You') last week.

Yesterday we heard a snippet from 'Glee''s upcoming "Teenage Dream" cover, and now the entire scene has been released online. Newbie Darren Criss serenades Kurt with the Katy Perry tune when Mr. Hummel transfer to an all-boys private school. Our favorite part: when Blaine adjusts the collar on Kurt's jacket -- super-adorable, and the kind of move that gets analyzed over and over again in countless teen magazines.

Katy Perry tweeted her approval, writing "Oh...My...Gosh... this just brought a sweet tear to my eye! Teenage Dream on GLEE makes my heart go WEEEEE!" Click through to watch.

One of the 'Glee' covers we were most looking forward to on the upcoming 'Glee: The Music, Volume 4' was a 'Glee'-ified take on Katy Perry's "Teenage Dream." Today, previews from next week's episode, "Never Been Kissed," leaked online and lo and behold, guess what tune made the cut?

'Glee' newbie Darren Criss takes the lead on the Katy Perry song. Since he's rumored to be Kurt's new boyfriend, we're guessing the lyrics are dedicated to McKinley High's fiercest fashionista.

The previews also include a Puck and Artie duet of "One Love," and two new mashups -- the boys take on "Stop! In the Name of Love" and "Free Your Mind" (which would be great without the out-of-place electric guitar roaring in the background) and the girls tackle "Livin' On a Prayer" and "Start Me Up" (which, due to the Bon Jovi, sounds very familiar).

The full lineup of songs on the fourth 'Glee' soundtrack album has been released on Spoiler TV, and it gives us plenty of clues as to what's coming next for the McKinley High gang.

Along with songs we've already heard, like "Empire State of Mind" and "I Want to Hold Your Hand," the new album features covers we've yet to listen to, like Katy Perry's "Teenage Dream" and "(I've Had) The Time Of My Life."

Most importantly, we've learned that forthcoming guest star Gwyneth Paltrow will cover Cee Lo Green's "Forget You," though it's unclear if that's a solo song of if she'll duet with someone special (ahem, Mr. Schue). The album will be released Nov. 30. The 'Glee' Christmas album comes out Nov. 16.

When you have a hit TV show, a bunch of best-selling albums and successful concert tour under your belt, what's next in monetizing your success? Why, a Christmas album, of course!

According to The Ausiello Files, 'Glee' will release its inevitable holiday-themed album on Nov. 16. That's a full three weeks before the show's Dec. 7 Yuletide special airs, giving the adoring public plenty of time to get into the Christmas spirit (and giving stores plenty of time to stockpile copies in advance of Black Friday).

Read on for the full tracklisting, along with the single the cast released last winter, "Last Christmas," which will appear on the album.

Saturday night's 'Glee' panel at the PaleyFest 2010 festival scored an all-time attendance record as a fire marshal's nightmare throng of screaming fans flooded into the Saban Theatre in Beverly Hills.

Other panels during this 2010 session served up enthusiastic crowds -- especially 'Lost' and Seth MacFarlane's appearance -- but the 'Glee' crowd had the feel of a rock concert gathering, producing more applause and squeals per creator and cast member than any event this year's PaleyFest provided.
