It seems like a logical move to add the ability to stream music to live-discovery apps like Songkick and Bandsintown. Not sure if you’re interested in a particular artist’s next gig? Try listening to some of their songs. Licensing is the barrier though: the growth of these companies has been aided by the fact that they’re not dependent on paying big advances for music rights. Cue partnerships like Bandsintown’s just-announced deal with Sony Network Entertainment, which will see the latter’s Music Unlimited adopted as the streaming music provider for Bandsintown’s apps. It’s a subscription-only service, but non-subscribers using the apps will be able to listen to preview samples of music from artists whose concerts they’re browsing. For Sony, it’s a new channel of marketing beyond its own devices – reminiscent of Rdio’s push last year through Shazam, albeit in a slightly-different discovery-app field.
