@ X61 not sure earlier bonapart said 'computer logic with string 1<12<13<131<132<14<2
you can do long push list to enter sorting mode and move all tracks by yourself
also you can rename tracks to 001,002,003..012,013 etc to have proper working sorting.
I ended up just deleting the problem file, will try agin later when i've properly tagged it on pc.

Used mussorgsky to tag album art and i have Joy Division Substance and New Order Substance and it's picked them up as the same
Substance then underneath New order/Joydivision. aint a clue how to sort that, even deleted substance( name ) from the New Order Folder???
