DJ Earworm - No One Takes Your Freedom (Scissor Sisters v. Beatles v. George Michael v. Aretha Franklin)
I think I can blame this mashup for my addiction. Gateway Mashup. From http://djearworm.com/category/frontpage/page/2
Combining the instrumental and some vox from The Beatles’ "Let It Be" and the acapella from Oasis’ "Don’t Look Back in Anger"
