I have a couple of albums with hidden pregap songs. For example on Rammstein's Reise, Reise album there's a hidden track before track 1 that I want to label track 0.
However, if I number that track 0, then it disappears and becomes blank when exiting and going back into MusicBee. So while every other song shows 1-01, 1-02, 1-03, etc on restarting MusicBee the pregap song that should show as 1-00 shows as 1- instead.
Doing the same thing but using 00 keeps the track as 00 and shows as 1-00 all the time.
Might not be a bug and just how the player is coded to handle a 0 as a blank, but I feel like 0 should be a valid entry that shouldn't disappear. This isn't a huge deal btw, just something I've noticed.
