If you'd wanted to shop Ubuntu One's Music Store in the past, you had to use a plugin through an app like Banshee or Rhythmbox. Not very convenient, we'd say. Someone must have been listening up in Canonical's cloud, as Ubuntu One just brought its 7digital-based store to the web and mobile devices. Apart from widening the software scope, it's billed as a more direct interface to shop for tunes and send them to Ubuntu One's cloud for either streaming or syncing. Don't think that's enough of a perk? Early purchasers get half a year's worth of Ubuntu One Music Streaming for free -- as strong an incentive as any to dip a toe into the (music) stream before jumping in.
