What music should I buy?

I got some itunes gift cards for Christmas and they’re burning a hole in my pocket! What music should I buy?

I enjoy many kinds of popular music. Here are some of my favorite performers. I’d like to find something fairly new (or even that sounds like one or a combination of them.

Ben Folds
Radiohead
The Beatles
Johnny Cash
Dolly Parton
The Flaming Lips
Modest Mouse
Death Cab for Cutie
The Killers
Weezer
Bobby McFerrin
The Presidents of the United States of America
Jimi Hendrix
Frank Sinatra
Neil Diamond
The Foo Fighters
Micky Avalon
Coldplay (I can’t help it, don’t make fun)
The Marshall Tucker Band
Aerosmith
Queen

I love tons more, but these are some of the ones which have been most consistently good for me. I also really enjoy Irish rock, bluegrass, some r&b, mellow rock (something like Granddaddy) and nothing in particular! Anything you can recommend that you think I’d enjoy, or that you really enjoy, I’ll look into. I’m so out of touch with music lately (disgraceful!) Greatly appreciate it!
