Technology watch:

Here's what I want, one day. Something like an iPod, where I can store a ton of audio files and, say, play it on "random," with the following features:

• I get to put files into categories and randomize within categories only, i.e., "randomize within Classical," or "randomize between Classical and Rock 50-50, and randomize within each category."



• I get to rate audio files, and the rating affects the probability that a piece gets played in the future, i.e. a "1" gets chosen rarely while a "5" gets chosen more often.

Does that exist, and if not, is someone working on this?
