This next song is from Rev Theory (formerly known as Revelation Theory). I did not like this song when I first heard it, but it grows on me more as I listen to it more often. This song is entitled "Hell Yeah"
This is another song off of Serj Tankian's (formally the lead singer for System of a Down) album. This song is their third single, entitled "Lie, lie, lie."
Cover Songs are opportunities to turn a good song into a great song, or just a new side of the song. Rasputina demonstrates this with their cover of Pink Floyd's "Wish You Were Here."
On a lighter note, cover songs can also give the opportunity to turn an absolutely horrible song into something fairly amusing. This is Rivethead's rendition of "Sexy Back."
