I don't listen to commercial radio anymore because it gets on my nerves. I am more than happy to pay my dues to KCRW or NPR so I can hear and learn about GOOD MUSIC, as opposed to craptacular music that unfornately seems to be more the norm these days.
Amos Lee is an artist I've just heard about -- from Darin, who's really good at picking out music I would like -- and I bought his album off iTunes. It's phenomenal. Go listen to it wherever you get your music samples. He's a little less California-y than Jack Johnson, but it's along that same vein -- stripped down, guitar-based, mellow, thoughtful stuff.
And Beck has a new album coming out too. It's going to be a great year.
