Google Play Music gets important experience improvements on Wear OS
The newest version of Google Play Music offers an improved experience thanks to the addition of the options to shuffle music and see what's playing next. Also, Google implemented a new download indicator that should help music lovers see what songs are available to download right to their smartwatches.
There might be some other minor changes, but these are all that have been mentioned by the search giant. Since Google doesn't say when the update is going to hit Wear OS, we must assume it's already available for download via Play Store.
