I;ve been using Google Music on my android device and it is by far the best music app I've used (vs. Pandora, spotify, last.fm, etc). The killer feature for me is that it learns what I like and the radio stations it generates are pretty awesome. This may be helped by the fact that I uploaded my entire mp3 library as well.
I recently bought a Nexus 7, and I had signed up for Google Play Music "All Access" immediately after it came out. The most useful feature, I think, is being able to store music from All Access on the tablet (for completely offline use, nonetheless!). To me, this is a fantastic deal.
Does the iPhone version allow for storage of All Access music offline?
I agree it's pretty good, but it's got its own share of bugs too. The most annoying ones are (on android, not sure if iDev versions behave the same):
- if you're close to no free storage space (close == ~20MB free), streaming won't work... this is bizarre in many ways, considering the app still has some other tracks cached locally and they're playable but not pinned
- it does not work well with other music apps. if you have google music playback stopped and switch to some other app (say, start playing some podcast) google music will force-stop the playback around every 10 seconds
- and the issue pretty much every app has... if you're stuck buffering, you cannot pause/stop the playback. the pause button is unresponsive until the streaming starts again :(
but otherwise... it's probably better than most other services. The linux version of the uploader could be improved a lot.
