I understand that through my Google drive account that I am accessing all of my music that currently lives in my DJ laptop. I'm a little confused in how the syncing works though. If I am am out and playing music off my phone, decide to edit a tracks tags or rating...how do I know that those changes will be carried over to my laptop next time I power it in and sync the files? How does the software know which version of a track to keep if, after changing one version on my phone, they are effectively now different files. So which one becomes the "master copy" so to speak?
