What am I listening to? What music do I like? I love statistics and trends. Guess it comes from being a Math minor way back when. I tried iLike a bit. Didn’t care too much for it, but it’s supposedly similar to Last.fm. Plus it has internet radio similar to Pandora. It doesn’t learn what you like nearly as quick as Pandora, but it shares it well.
