My top 5 favorite performers in no particular order
Sidney, Deryck, Steven, Ryan Key & Oli.
& The worst (not really bad but..).
J. Davis - His voice is great but a song like OSC is not for him, dude can't scream.
No Doubt - They changed the genre of COG... it felt like a funk jam
Taka - He forced his voice a lot, kudos for trying
Choosing BID for M. Shadows: He nailed it but his amazing voice could have sounded better in another song
Blink 182 - Why did they play WID? that song just doesnt suits them, it made them look bad.
