"A Strange Light from the East - Eastern Influenced Western Music
(1965-72) - CD2 - 07 - Rascals - Sattva.mp3 (1/43)": unquotedName cut at
the last " - " ("Sattva.mp3"), leaving track number and artist in the
subject, so every track was a release (85665085, 85665050). With a
" - NN - " track or part number the name starts there ("07 - Rascals -
Sattva.mp3"), the rest names the album and disc. Both implementations;
tests; fixtures identical.
