It would be nice if the track numbers are ordered separately by their disc number.
If there is an album with two discs and three tracks on each disc,
it would be like,
Disc 1
1. Track 1-1
2. Track 1-2
3. Track 1-3
Disc 2
1. Track 2-1
2. Track 2-2
3. Track 2-3
When I put this album into VOX, it shows,
1. Track 1-1
2. Track 1-2
3. Track 1-3
4. Track 2-1
5. Track 2-2
6. Track 2-3
It would be better if it showed
1. Track 1-1
2. Track 1-2
3. Track 1-3
1. Track 2-1
2. Track 2-2
3. Track 2-3
so that the user can recognize the disc number.
