For people wondering why you can't create an account – WiMP Review

It says on this app that you have to install another app called "TIDAL" and then your username and password from tidal is the same for "WiMP" I really haven't tried it out so I don't know how good the app is, but yeah, that's why. So you'd have to get "TIDAL" in order to log into "WiMP".
