A month or so ago, an acquaintance who has forgotten more songs than I will ever listen to in my life told me about this UK site.
Now, via Meg at Blogcabin: Pandora.
The idea of both sites is that you tell them what sort of songs you like, and they assemble a “radio station” that streams similar music. You can refine the “station” they build for you by giving feedback (e.g. by banning a song that grates on you). You can also share the station/s you’ve created with friends.
What a great way to explore music. What a perfect example of how technology can offset the homogenization that tends to result from mass market commerce models. And we didn’t even need to wait for the Singularity :-D
