if not for the work requirement, at 80gb you could likely do what I do: use syncthing to make there be a full copy of the files on your phone. I've got a media terminal, my laptop, and my phone each keeping each other up to date. it's never broken or been frustrating. it works offline perfectly.

Hmmm... I could. Substreamer let's me mark albums and playlists as "offline access" so I have something local. That works well enough.

Syncthing for photos is awesome. When I cut-paste on my desktop they are removed from my phone too.
