Did you get Jack's new album just released Yesterday? It's a worthwhile pickup.
I'd also recommend the following:
Mason Jennings- Use Your voice, Self-titled, Century Spring, other one
Ben Kweller- Sha Sha, On my Way
Jason Mraz- Waiting for my rocket to come
Kings of Leon- I think its called "California"
Gavin Degraw- Chariot
Josh Ritter- Hello Starling
David Gray- White Ladder, and there's another one but the name escapes me
Donavan Frankenreiter- Self-titled
G.Love- Greatest Hits
I like your taste in music (except for Fionna). Way overrated in my opinion, but what do I know? I'm just a kid.
