Lillian sent me a link to Amazon.com's Music Download section today. I'd downloaded a couple Tom Wehrle songs from there a long time ago and they came embedded w/ voiceovers for Amazon, so I didn't go back (although I kept the Wehrle MP3s and edited out the voiceovers using Audacity ;)). But, Lil told me that they've repented of their evil ways and the MP3s are now pure, so I checked it out. They've got some pretty good stuff there: Joss Stone, Pennywise, Modest Mouse, Tom Waits, the Dropkick Murphys, the Slackers, etc.
While we're on the free music kick, PunkBands.com has a few good Flogging Molly MP3s this month.
