The medical drama 'House' (Mon., 8PM ET on Fox) can be a fairly tense show. So occasionally, it's just nice to sit back, relax, and listen to the characters sing really badly.

Which is pretty much what happens on the latest episode.

Yes, there's a plot. But there's also bad singing, which is even more important.

American Idol is a show that takes virtual unknowns and creates stars. Even a couple of judges (Randy and Simon), and a host named Ryan Seacrest became household names thanks to Idol's success.

But there's one guy of vital importance to the show who isn't so well known. Most of the time he stays in the background. But there wouldn't be any Idol music without him. He's Idol's inhouse musical director -- Rickey Minor.
