On Thursday, March 7, FOX will be all about the music. That night will feature a special 90-minute episode of “American Idol” in which the Season 12 finalists will be revealed, followed by a “Glee” episode containing the show’s 500th musical performance.

So very much music!

“American Idol” will begin the night, airing from 8-9:30pm (live ET, delayed PT). On the episode, audience votes will be announced in order to choose those singers who will advance to the finals of the show.

After this, “Glee” will air at 9:30pm for the “Girls (and Boys) on Film” episode. In this installment, the members of New Directions have to choose a song from a movie to sing. The 500th performance will “Shout,” the anthem from “Animal House.” Meanwhile, over in New York City, Santana (Naya Rivera) settles in to the apartment with Kurt (Chris Colfer) and Rachel (Lea Michele). She might, in fact, be getting a little **too comfortable.

What other songs might be featured in the show? Which “American Idol” contestants have the best chance of making the finals? We will find out in March!
