Gaming the system

Finally downloaded a new set of results from the beta iTunes Music Recommendation system. My previous run was more amusing than useful, but it had potential.

This time? Utter nonsense. Some clowns decided to corrupt the database by uploading garbage. There’s no other reasonable explanation for the results I got, in which the first 32 of 50 tracks recommended all come from albums named “Unreleased” by such famous bands as Syph Clap and the Orgasmic Meatrats, Marc Coulter, z..Marco, and Vital Cry.

If they allow this to continue, in a few months their data might be as unreliable as CDDB.

Update: things have improved, either through database maintenance or, as the creator would have it, the natural consequences of increasing the size of the database. I’m betting on the former, myself. Suddenly all the garbage went away, restoring the results to the quality of my initial run. Much faster now, too, enough to justify spending a little time tinkering with the data to see what happens.
