This is a bummer. I gather that I'm one of the few users of Google Play Music, so it's not surprising it's being killed. But it was one of the few streaming services that had the ability to upload your own music, a good catalog, and widespread device support.

YouTube music is OK, but worse in a bunch of respects. It separates out your uploaded music into a separate library (admittedly the matching in Play Music was always a bit wonky, but better than just giving up on the problem) which makes finding and managing music much more annoying. The UI is also really, really slow. Tt loads a single page of albums / songs / whatever at a time and takes a second to load the next one.

This can turn the process of scrolling through your albums, which has been effortless since iTunes debuted, into a multi-minute process. I've been hoping ever since they announced the switch that they would improve this stuff but it doesn't look like they've made any progress.
