I created something similar a couple of years ago: http://www.nocurve.com/musicmap/

If anyone is interested in how it was implemented: http://nocurve.com/fun-with-data/data-mining-on-freedb/

Agreed, music map is a great interactive way to discover music. Last year one of our internal hack week teams built something like that using our vector space model. What was cool is you could switch between the different types from the UI, e.g. Nirvana -> Red Hot Chili Peppers -> DC101 Alternative Rock. You could also start stations from the UI - it was really fun discovering music with it!

Thanks - this is just what I need. I listen to old rock and roll, new age jazz, texas swing, country gospel and so much more...

I tried Santana, Mountain, Ten Years After, Alison Krauss and Union Station, Asleep at the Wheel

I see bands I like and some new ones to try. I'm going to use this to create some new google play playlists for my commute.

Thank you so much.

[EDIT] typo

It works best on more mainstream and established acts. It falls apart on artists with fewer sales/visibility.
