I won't be enticed by your advances, as that would result in you stop posting.
Metallica are legendary? I dunno about that. They were once a respectable band that should've given it up years ago, just like U2. Should've fucked off years ago.
Meh, mixed bag.
I don't like The Mars Volta, I slightly prefer ATDI.
Muse are good.
ALL R&B? Do you mean all contemporary R&B or just R&B full stop?
Most Emo is shit, I'd say over 90%. Bits and bobs out there that's pretty good though, but not really my thing.
!!! are a bit rubbish.
TV On The Radio are okay, not 'love worthy' though.
Maroon 5 are God awful.
Ryan Adams is a little boring.
Never been able to really get into Cake, probably listened to the wrong album or summin' but what I heard I thought was poor.
Drive-By Truckers, same as Cake really. Picked an album at random, Pizza Deliverance I think and it wasn't bad... but I didn't feel the need to listen to them again.
But you like Modest Mouse, QOTSA and Nick Cave so you're not all bad.
