Messaging app Tango is beefing up its music partnerships, launching new channels within its app for Rhapsody, SoundCloud and Vevo yesterday, who join existing partners Spotify and 8tracks. All of these companies now have “channels” within the Tango app, which combines WhatsApp-style messaging with Skype-style internet calls, and has more than 200m registered users. Its music partners can sign up people to follow their channels, get alerts on new songs and videos, and share the ones they like with friends on the service. “We’re going big on music and entertainment, and excited about the popular brands we’ve been able to add into Channels,” said CEO Uri Raz in a statement, adding in an interview with TechCrunch that music, entertainment and celebrity channels have signed up 5.5m followers collectively since June. Tango has been the most active of the big messaging apps in striking deals with digital music services, although in Japan and Korea, Line and KakaoTalk have been working on their own-brand music offerings.
