Here is why I am still subscribed (and actively use) @GooglePlayMusic:
1. @youtubemusic isn't even close to being ready to replace GPM.
2. I haven't gone anywhere in the world (so far) that has restricted my access to the product I've paid for (YTM needs to figure this out) /1
3. Sometimes when I play new music on YTM on a Bluetooth speaker, the song plays with no volume and I have to pause & unpause for it to play.
4. Playing/Loading songs isn't as seamless as on GPM. It takes longer to play on YTM.
