You don't understand. I'm saying you can't listen to your Google Music collection offline unless you pin your music beforehand. And the reason why I brought this up a while ago in this thread is because we started to discuss the importance, at least for me, of locally stored music. I'm not saying anything about playing music stored locally via Google Music.
How is that different from downloading the music off music match or loading music into an iPhone? You still have to transfer music to an iPhone via iTunes to get songs in its not on there by default and it has to get on there somehow.
With google play, a brand new android phone, you can have all your songs and playlistst from iTunes or your music collection on there and listen to it offline once its loaded into the phone.
What's the issue here?
