For people wondering why you cant create an account
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 havent tried it out so I dont know how good the app is, but yeah, thats why. So youd have to get "TIDAL" in order to log into "WiMP".
