Most of my mp3s display in the correct order - I have different views set up that group by Album and then sort by Track #, for the vast majority of my albums this works perfectl, but there are odd ones that throw the tracks out of order (one example is a 17 track album that has everything in the correct order apart from tracks 6 and 12 which appear at the bottom of the list). I have tried deleting from the library and reimporting, retagging the Track# (if I make track 6 - which appears as the penultimate track - track 21 then it moves it to the bottom of the list, but if I make it any track between 1 and 17 it keeps it as the penultimate track). The filename matches all my other filenames in structure (which is created through MC). I am completely baffled. I'm using MC 14.0.165, but this has been happening for previous versions as well. I've got 9,076 albums all tagged perfectly (at least consistently) and this is happening on probably about 200 of them. The major annoyance is because the tracks are out of sequence they show up on my 'incomplete albums' view (an external hard disc failure caused me to lose some tracks and I want to restore them form my backup files, by running a check for incomplete albums, but that view is corrupted by these odd track anomolies). Anyone got any ideas?
