We've got multiple Nexus 7's in our household (kids), and I'm having a hard time figuring out the best way to manage the different music collections of the different people. Many of the songs will be from CD's, from Amazon, from iTunes (DRM free) and new purchases on the Nexus 7. It is a nightmare trying to manage it with different Chrome accounts on the same home computer -- because Music Manager is not suited for this. It won't let you identify certain folders for certain people. It treats the whole computer as the same for everbody. I'm thinking of going to a "drag and drop" method for everybody. I'll just create folders for different people, then if I want a song on a device, hook the Nexus 7 via USB to the computer and drag and drop the song onto the device. But will Google Music work like this? Am I going to have to switch the music app from Google Music (on a Google device, no less), just to avoid hassle in a multi-user, family environment?
