Last.fm API integration

For more information or to ask questions about this proposal, see http://groups.drupal.org/node/9956.

This project would entail integration with the APIs for the music social networking site last.fm. The list of their available functionality is here:

There are two loose classes of data. Music data (artist/album/track/tag) and profile information (my last tracks played, my most popular artists, etc.) I'd love to see both groups get implemented but either would be really useful. The former is probably a bit easier since it doesn't deal with the authentication process. One particularly interesting set of data is the concert listings for a musician, as well as the concerts users are attending (and recommendations for concerts they would like.) This could get mashed up in all sorts of cool ways.
