Looking at the price of the Groove Music Pass, wouldn't people just use MixRadio for free on Windows Mobile?
Sure, if all you want is the radio side (does cost though if you want ad free), there probably others as well just as good for free

For me the Music Pass is value as I can add virtually any music from the catalogue into my local library, much cheaper than buying multiple albums each month (obviously if I do cancel I lose this music)
I prefer to listen to albums instead of just individual songs
