I had the same problem and found a workaround. Play the playlist on your phone but use the "connect to device" option to send the output to to your pc. It may not be worth the hassle but if you have a new iphone with no headphone jack or you want to play through larger speakers, it may be worthwhile
Aren't you an ungrateful person. Yes, I waited for this for a long time as well but now that it's finally here I'm just happy! You could have anyways used it on desktop by directing phone output to desktop.
