Philip,
MTP kioslave whould be certainly beneficial for Amarok too, as its current MTP-
collection is pretty much unmaintained.

Would copying music files in Dolphin to a MTP device using your kioslave suffice 
for the device to find it (and display its metadata)? Is so, Amarok's USB Mass 
Storage collection shouldn't be hard to extend to handle such devices. If it 
wouldn't be that simple, we should find a way how to set MTP-compatible 
metadata for transferred songs. (see KIO::Job::metaData())

Philip, also please take look at https://git.reviewboard.kde.org/r/103028/ 
which deals with MTP device detection in Solid.
