I don't particularly care for using the term "best of," because art is so subjective that I can't tell you what the best was. And I certainly can't say that they're my absolute favorites from the year because there is so much else that I didn't see. So here are some of my favorites of 2009, in no particular order.

Most of the "new" bands I get into are buried treasure artists that haven't released in album in 20+ years, so I am so not up-to-date on current music. That was made even more apparent to me when I realized looking through the albums that came out last year that 1) I don't know at least half the bands on most critics' Top 10 lists and 2) that there are an awful lot of bands that I like that released new material that I wasn't even aware of. Bands like the Yeah Yeah Yeahs, The Flaming Lips, Sonic Youth, even Kiss. Also of note, though not on an album yet, Devo released a few new songs that's some of the best material they've done in years.

I may post some additional favorites of 2009, but this is a good list so far. What other "favorites" categories can I do?
