If you have not stumbled upon this yet, let me introduce Pandora, possibly the coolest thing on the web. Pandora is, among other things, a radio developped by the Music Genome project.
I'll keep the explanation short and sweet:
On January 6, 2000 a group of musicians and music-loving technologists came together with the idea of creating the most comprehensive analysis of music ever.
This lead to the creation of Pandora Radio. The concept has immense possibilities if it works... and it does.
Ever since we started the Music Genome Project, our friends would ask:
Can you help me discover more music that I'll like?
Those questions often evolved into great conversations. Each friend told us their favorite artists and songs, explored the music we suggested, gave us feedback, and we in turn made new suggestions. Everybody started joking that we were now their personal DJs.
We created Pandora so that we can have that same kind of conversation with you.
You have to register(invent a zip code if not from US), but it's painless and they don't send crap.
So beautifully 2.0...I just love it. Enjoy!
