From Uber and Tinder to Headspace, Spotify has been working hard to forge partnerships with other kinds of apps to keep its customer-acquisition machine purring. Its latest partner is the video-streaming app for US pay-TV network Starz. The idea is that Starz viewers will be able to discover and stream soundtracks for TV shows and films from within its app – although they’ll need to be paying Spotify subscribers to listen to songs in full. Starz is creating playlists for some of its original shows, with the likes of Flesh and Bone, Da Vinci’s Demons, The White Queen and Spartacus all getting their own Spotify soundtracks as part of the launch. It’s another hint at the future breaking down of the walls between music and video-streaming services, especially independent ones that aren’t owned by a tech giant like Apple, Google or Amazon – all three of which have the potential to one day offer bundled video and music services of their own.
