After months of only listening to music on Pandora, I just fired up iTunes, and keep trying to rate every song. How else is iTunes going to know what to play and what not to play?

Instead of just deleting the songs I don’t like — or awkwardly assigning 5-star ratings to the good songs — I’m left wondering if Mahout could do an okay job with recommendations based solely on the information in the music’s metadata, like artist and genre.

And then I realized that other users could share their ratings to help recommend songs that might already be in your library, I accidentally re-invented Ping, which I find troublesome and creepy. Dammit.
