Streaming service Deezer is making a big play for more developers to build apps on its platform today, with a series of announcements. They include an affiliate scheme to reward developers with “a payment equivalent to a month’s Deezer subscription” whenever their app refers someone to the service who signs up for a subscription. Deezer is also beefing up its APIs for third-party apps, including showing activity within them in its social bar, and new features to support music games that tap Deezer’s catalogue. To show off the latter, Deezer is launching its own SongPop-style Askking Music [sic] music identification game. Finally, Deezer is rolling its App Studio platform out for iOS and Android, to encourage developers to build apps that work within its mobile and tablet apps – getting in ahead of Spotify on this count. Deezer says 35 apps have already been developed for its web platform in the last six months, but it’s now in an arms race with Spotify to ensure developers, startups and labels support its platform. Keep an eye on the affiliate scheme in this regard: could it offer a way for artists to make money from driving their fans towards Deezer?
