Craig asked for an RSS feed for his iTunes so he could share what he was listening to. Turns out that’s a feature of Audioscrobbler, the community app for sharing your playlists. With a simple plug-in for iTunes for Windows or the Mac, you can upload everything you’ve listened to, and your friends can subscribe to the content in RSS (1.0).
Frinstance, here’s my Audioscrobbler feed. The only problem: what do you do with the information once you have it? Here Audioscrobbler is missing an opportunity. An automatic “buy on iTunes” or link to a tune excerpt, where available, might be pretty damn cool—and might make some money.
