Finetune has launched a new “streaming DJ” service, Finetune Live.  I’ll let the site speak for itself, but basically the service allows you to broadcast what you are currently listening to on iTunes, and anyone viewing your profile on Finetune Live can tune in to your stream.  It’s still in beta (I think?), but has worked for me with no problems.

In the past I’ve streamed music via running an icecast server, but Finetune Live brings the same basic streaming idea to a more user-friendly, high-discoverability medium.  It will be interesting to see where this goes, as I can imagine this sort of product would be very attractive to Facebook users, MySpace users, bloggers, and other self-promoters.
