In case you haven't seen it yet, Muxtape is a wonderful, ultra-simple, fairly illegal mixtape-sharing site. Upload 12 mp3s, arrange them, pick a header colour and thy're there for the world to stream. There's no easier way to share you music (or anyone else's.) My 'spring is here, haul the barbecue up from the cellar' mix is at musicthing.muxtape.com. Where's yours?
