I have entire albums of songs that are confusing to sort through when sorted alphabetically - I know where in the tack listing they should be, and always get lost looking alphabetically. My current work-around of adding the track number to the track name obviously makes the 'songs' tab pretty useless. I could just use the 'custom' field, but I don't know if that would let me 'sort by', and it feels like such a basic library function that it should be included any way?

Maybe I'm missing something, but if there is a way to do it, it's not obvious (as I'm pretty sure 'song ID' isn't what I want, unless I misread things).
