Well... I can tell you I'm NOT listening to my cellphone playlist on GooglePlay anymore, because they got rid of GooglePlay music and replaced it with that joke of an app, YouTube music. You see, YouTube Music DOES NOT just transfer your playlist over from GooglePlay music for the songs you have on your phone. In fact, it DOES lie, and tell you it's transferring, but when you open YouTube music...SURPRISE!!...NO PLAYLIST SONGS. Oh, no...you see, YouTube wants you to RECREATE your playlist using THEIR DYNAMIC...and I'm sure subsequent costs as well. So I killed YouTube Music, downloaded Audify, and it works perfectly. So, in summation. GET RID OF or DON'T GET YouTube Music if you want to listen to your cellphone playlists on bluetooth. Get AUDIFY instead.
