I do roughly the same thing, but I use Syncthing. I always had trouble keeping my phone connected reliably enough to run a long running script, and Syncthing works well. I have a 1TB sdcard in my phone that has a mirror of my 600GB+ library. I use Foobar2000 on my phone because it's easy to just pin my Music folder from the filesystem and navigate through the folders. Just about every other music player out there seems to be designed around importing tags into a library, which I don't like.
