Actually I've been wondering how the Android MTP stack and the
Samsung MTP stack handles metadata.

It seems to me like you can indeed in most cases query tracks for
metadata over MTP, but when sending metadata it seems to be
ignored on some devices, and the proper way to get that in place
is to have tags in the files.
