I forgot one of the BEST sites out there. For bands with a webmaster, www.audiogalaxy.com/backstage will give you 50 MB of free space. You really need to know html for this, as there isn't an editor with it, you just upload stuff.
Check out their home page at www.audiogalaxy.com for an idea of what they offer.
I did a site for Between the Worlds there, and put up one free mp3, with all the other mp3 links going offsite. Have a look.
