VOX 2.1
OS X 10.7.5
To reproduce: Select a range of files from a folder in the “Add Files” dialog. Adding an entire folder by selecting it and choosing “Add” seems to work correctly.
Interestingly, tracks within a folder are always added in the same incorrect order. My files are named with a track number prefix, so an alphabetical sort would put them in the correct track order. The order VOX chooses doesn’t seem to correlate to file size, last modified time, or anything I can see. This is the order for an example album:
08 Reverse Running.flac
07 Judge Jury and Executioner.flac
05 Unless.flac
01 Before Your Very Eyes....flac
03 Ingenue.flac
04 Dropped.flac
09 Amok.flac
02 Default.flac
06 Stuck Together Pieces.flac
Also, the numerals in two-digit track numbers are displayed stacked vertically instead of side-by-side.
