I would love to have an intelligent playlist generator like the Flookey program.
helps you to create meaningful playlists
provides efficient navigation through your personal song library
adapts to your personal listening preferences and suggests songs from your private library
creates dynamic and adjustable playlists from your private collection
detects similarities between between your songs based on audio analysis, meta data, and your listening preferences
Sadly this good idea is no more. think it was a school project or something like that.
You can test the idea at http://flookey.jkilian.de/
