Lets see, albums released this year I've purchased are:
And you will Know us by the Trail of Dead - Source Tags & Codes
Beck - Sea Change
Flaming Lips - Yoshimi...
Weezer - Maladroit
Wilco - Yankee Hotel Foxtrot
I guess those would be by favorites, except the Weezer albums isn't so good. From I've stuff I've listened to but don't own, I've liked albums by Sigur Ros, Interpol, Hot Hot Heat, Badly Drawn Boy, Blackilicious, Tom Waits, Queens of the Stone Age, Jurassic 5, and maybe some others.
