Multiple errors in log (paths and tags look ok)

Thanks for all this information.

For the track that produces errors in two playlists but not in a third playlist, is the relative path in all three playlists identical? Also, are all three playlists in the same folder?

Please also try changing your contentDir setting to just /volume1/music and doing a rescan. Does this make any difference to the problem?
