Very interesting read. I actually found it when searching for Audioscrobbler. it ranks pretty high on Google.

IMHO, you're right from one point (tried and got to like songs which are completely different then the ones I normally hear) on the other hand Audioscrobbler is interesting in the sense, that it gathers information about your listening habits (which song do I play the most?) which could be a possibility to change, and: I've found really great music browsing other people's lists in Audiogalaxy, which happened to have a song in them I was looking for.

Aaaah, Audiogalaxy :-(
