MOG adds free music gas tank to subscription plan

LOS ANGELES (AP) ? MOG, a subscription music service based in Berkeley, Calif., says it is introducing a free music service that will supplement its $5-a-month unlimited streaming plan and $10-a-month unlimited mobile music offering.

All that tweeting and sharing of photos on Facebook could finally have a tangible reward: free music.

Starting immediately, MOG is giving new users a kind of digital gas tank they can use to listen to tracks from its library of 11 million songs. Sharing songs, making playlists and other actions get users more gas.

MOG’s free system revamps what was a 14-day free trial and puts it in competition with Spotify, which has a free service that is limited by time caps in some countries.
