With the recent release of itunes 8 and it's built in genius feature, it would seem that my work on similar playlist creation has become outdated. However, there is one thing that genius lacks: a feature that allows exploration of similar music apart from my own collection. Of course, there are suggestions from the itunes store, and I can preview 30 seconds from each of these songs, but that's not always a good indication of whether I'll like the song or not. So I decided to write a quick little program to combine the features of last.fm's similar tracks functionality and seeqpod's playable search. Here's the result. It's ugly, but it's functional (as far as I've tested it). As always, interest will dictate how much additional work goes into the program.
Requires .Net framework
To run the program, unzip the folder, run the .exe file, and select a track in itunes. Then click on the "Generate List" button to start listening to new music!
