MOG demo'd the next version of their popular music service to me today, and I was impressed. It combines a best of breed interface with free on demand streaming and a Pandora-like music recommendation engine. The trouble is, it may never launch because only two of the four major music labels are supporting it so far. MOG has a history of doing cool new things around music. The service today includes a media player plugin that records and analyzes your music habits, a website that has a dedicated page for every artist, album and song with user generated reviews and posts, and an advertising network that provides revenue for 300 top music blogs. Users can also stream music via an excellent front end to Rhapsody . All of that brings about 5 million unique visitors a month to their network, and the company says they should bring in about $5 million in revenue in 2009.
