The app first try to match your music with Google catalog, if they couldn't find the music they will upload the musicI've been using Music on my N4 and like it. I'm considering downloding the app for my iMac, but I'd like to know exactly how it sucks up the music on the machine and whether there are any downsides. For example, does it actually upload all of my songs, or does it just look for matches in Google's catalog and then use those when I'm accessing Music on another device?
