Listener-annotated audio with SpotDJ

Do you like the way that radio introduces music before you listen to a song? Do you miss that kind of personalized introduction in iTunes? SpotDJ offers a new way to bring the human warmth and information richness of radio intro spots into your iTunes listening experience.

To get started, you'll need to sign up for a SpotDJ account and then download either the Mac or Windows client. After installation, you launch the client and log into your SpotDJ account. The software automatically detects when you're listening to music in iTunes, and adds "spots" between tracks.

If the mood so takes you, you can join in the DJ club by recording your own spots and uploading them to SpotDJ. I was pleasantly surprised by the quality of the available spots I listened to. SpotDJ offers a star rating system for spots to help promote the better spots and DJs and to put limits on the bad ones.

This is Web 2.0 in all its glory. Social computing applied to iTunes.
