There are a lot of great bands they never plays songs from on that show that I think they should. For instance: Led Zeppelin, AC/DC, Aerosmith. But yet they've played like 3 or 4 Coldplay songs, which I've got nothing against Coldplay, but still, the contestants should be playing real rock n roll.
They should have been named SuperDiva Popstar. Full of shit. Neither of them could sing any GNR song except for Don't Cry. Metallica and metal is just another story... Singing Nirvana badly and nearly crying Coldplay covers don't make someone with bad make-up suddenly a rockstar.
