I've written in the past that I like mashups. A friend of mine recently shared a version of will.i.am and Britney Spears' "Scream & Shout" mixed with Eminem, Hilary Duff and Lady Gaga:
It's bizarre, but it's fun. The only part I was confused by was a lyric from "The Bad Touch" by Bloodhound Gang, as it didn't seem to fit in with the rest of the mashup; it didn't spoil the song, though. I had to look the lyric up to see what song the lyric came from and who sang it.
