Aerial And Trail EP on eMusic
I also wanted to mention that Aerial And Trail is on eMusic.
Still to go: iTunes, Napster, Amie Street, lala, Rhapsody, Shockhound and Limewire. If you find it on any of these services let me know so I can update the list. I'll send you a high-quality (.wav) version of the album if you do. I'm nice like that.
