Mog, the Berkeley, CA-based music community site, has taken a $2.8 million strategic investment from Universal Music Group, Sony BMG, as well as various angels. The site, which competes with sites like iMeem and iLike, was started by David Hyman, formerly of Gracenote, which recently announced a sale to Sony (NYSE: SNE). According to VentureBeat, which first reported the news, it has previously raised $3.2 million over two angel rounds, for a total of $6 million. Last December, the company announced a partnership with Rhapsody allowing bloggers to share and discover new music.
