I'm using Blip.fm to create an indie radio channel, providing the option to stream the music posted. A few tracks aren't available on there - some of the more obscure indie stuff and Peel Sessions etc - but hopefully it makes it easier to sample tracks prior to coming back ti the indie music blog here to download free indie mp3s.
You can click-through to play individual songs from the widget below or listen to the entire stream by checking out my indie radio 'station' at blip.fm/occasionalrain
