I checked buzzshout with "the stranglers" and "cabaret voltaire". for someone who is interested in non mainstream music some criterias you use (tempo, frequencies etc) is not relevant to my taste of music - i am interested in the emotional content of music - difficult to measure. the only solution is user rating of personal musical taste. the ability to be a learning system - semantic music network is offered by other platforms too - musicovery.com including a personal radiostream. etc. but still your service is interesting & last but not least for free!

i like the idea to receive personalized music by rss-feed.
