Does anyone know which glee music album the song Jessie's Girl is in?

If you want the version from "Laryngitis", then you might want to get "Glee: The Music, The Best of Season One". But it's available in Holland and the United Kingdom (I'm not sure about anywhere else).

If you want the version from the concert movie, you're gonna want to get "Glee: The 3D Concert Movie Motion Picture Soundtrack".

The song was not released on an album that you can physically go out and buy. You can buy the single on iTunes, and it's also part of the digital-only iTunes exclusive album "The Complete Season One" which is a compilation album of 100 Season 1 songs.
