Glee RachelIt's no secret that everyone loves the music in 'Glee' -- and 'Glee, The Music, Volume 1' has been quite a popular fall release. And how could it not be? It runs the gamut from the Supremes' 'You Keep Me Hangin' On' and Young MC's eternal club hit 'Bust a Move' to REO Speedwagon's 'Can't Fight This Feeling.' But what's made the soundtrack even more successful -- besides the way that the music incorporates itself into the plot lines -- is that it poaches from the last forty years of pop music, giving a little bit for everyone.
