GraphBrainz Extension: Last.fm
Retrieve artist, release, and recording information from Last.fm.
The extension works by sending the MBIDs of entities to the Last.fm API
whenever their lastFM field is requested. Only entities with known MBIDs on
Last.fm will have their lastFM field, otherwise it will be null.
