Coldplay, Kanye, Nicki Minaj, Madonna and Usher have all turned their profiles blue to shill for the new streaming service on Twitter:

So what the hell is Tidal?
Tidal was a tiny Norwegian streaming service that basically no-one had heard of, until Jay-Z bought it (and parent company Aspiro) in January. The service is meant to offer a premium streaming experience, with 25 million high-definition tracks offered in lossless format, for a fairly steep $US20 a month.
Maybe he got them free subscriptions or something?
