@jonas I experimented a bit.

A restart of Strawberry resolves the issue - afterwards the order is as it should. I can live with that. I am happy to help debug though.

The reported behaviour is only visible when the files on disk are changed - e.g. the file 03.Frank Sinatra-New York New York.mp3 is replaced on disk with a new version, and either an update of the changed collection files or a full collection rescan was performed.

LC_COLLATE is set to POSIX.
All the meta data is set identically (disc number, year, album artist, genre etc.). Only the fields Track and Title are different.

As an aside: I also updated to 1.1.3. Should I redo my testing (was still made on 1.1.2)?

@jonas It is set by Advanced Grouping, with Level 1 set to Album Artist, Level 2 set to Album and Level 3 set to None (for the lack of "Track Number".

All songs are set to correct numbers, verified by EyeD3 and Foobar2000 (to check via two different OSes).

Hello!
Is there a way to set / get the sort order of songs inside an album to be according to either file name or maybe by track number? Right it seems to be by reverse file creation.

Use case: I found that 3 tracks (2, 5 and 7) out of an album had some quality issues, and re-ripped them from CD. Now they are listed before the existing ones, despite a full rescan - and when I add the album to the playlist, the track order in the playlist is 2, 5, 7, 1, 3, 4, 6, 8, 9.

Thanks!
