I don't subscribe to the magazine (yet), but thought I'd give a plug for a nice feature on the Performing Songwriter magazine webiste. It's there Top 12 DIY section (archived back to Jan/Feb 2006) that showcases independent songwriters who have released an album without the backing of a label. If that's you, there's a link on the page that invites you to send your CD in for a chance to be featured.
Good luck! (Me? I'm still working on putting together a CD...)
