According to Bloomberg Apple Music will be getting a major revamp and 9 to 5 Mac who has a great track recorded says the app is due a for a full overhaul. Apple is suppose to be focusing on features like lyrics, black and white design, and artwork. I will wait to pass judgment until I see it, but this is great news for those of us that stuck with Apple Music after the three month trial.
To be honest I am not a big fan of any one streaming service, I find all of the layouts very cumbersome. I don't ever use Apple Music Connect or Radio, though I doubt they will drop those feature I wouldn't mind being able to hide the features I don't use. So if Apple does makes a solid UI in the app I will be very excited. Right now I mostly use Apple Music with Siri, and that for me is the biggest compelling feature to keep Apple Music around. Reports say we will see something come June at WWDC.
PRO Tip: If you go into the restriction in the settings app and turn off Apple Music Connect it will be replaced by the far more useful playlist button.
