Chris has passed me the musical baton, and I must comply:

Total volume of music files on my computer:
I have files on my mac at work, and my PC at home. We'll go with the mac, since that's what I'm using now: 2350 songs, 5.8 days, 8.61GB

The last CD I bought was:
It's Yours To Keep, by Loquat

Song playing right now:
Woven Birds, by Calexico

Five songs I listen to a lot, or that mean a lot to me:
This is a hard one to answer. There are so many I could list, but this will do for now:
1. After the Afterlife, by Chad Van Gaalen
2. Red Right Ankle, by the Decemberists
3. Peach, Plum, Pear, by Joanna Newsom
4. Capital A, by Lois
5. Baby Blue Sedan, by Modest Mouse

Five people to whom I am passing the baton:
