Soundcloud

I just got a Soundcloud beta invite from Rich and I've been playing around with uploading tracks from Isometric Dancefloor, my free net release of video game-inspired lo-fi trance. The whole thing will be on there eventually for you to download.

Soundcloud is a service which makes sharing and commenting on music very easy - it does this by having a very simple interface which facilitates fast uploading and sending of tracks. One feature I really like is the ability to tag different sections of tracks with comments: the track is displayed as a waveform - simply click the part of the tune you want to tag and add an inane comment.

I'd recommend checking it out if you're musically inclined and you can snag an invite from someone.
