Came across this mash up of three songs - Love the way you lie by Rihanna featuring Eminem, Taio Cruz's Dynamite and Tennage Dreams by Katy Perry.
Sounds pretty good except till the end where he really mashed all the songs up, singing them together. That's when it got a little messy IMHO.
Still, 3 song in 1, not bad.
Me? 1 song? It would take a miracle. =p
