If Google has that exact track it will match it. If it doesn't, it will upload your file and use the information on the file for naming and such.1) With respect to streaming your local music, is it a case of Google matching what is in their library? For example, I might have five different bootlegs of the same song (all tagged appropriately), not released through record labels. How does Google Music handle that?
As far as I can tell, you can only stream radio stations. They're infinitely long, in theory, so I don't know how you could cache them. You can create a playlist of both your own tracks and Google Music tracks and then cache that, but you'd have to know ahead of time what you want on there.Can someone confirm if you can cache radio stations for offline playback? I'm a bit confused on whether (or how) this works
