MusicWeek reported that ad-supported music service and download store, We7, which Peter Gabriel co-founded, is rolling out a new monetization model whereby its users get rewarded with points for their session time which can be redeemed for ad-free days of music.  In addition, an ad-free subscription service will be offered as the portal’s premium tier.  The news comes just shy of SpiralFrog’s announcement last month that it will be shutting down.  SpiralFrog, a competing ad-supported music service, was unable to sustain its business model.
