I like to sort my library by date created so the newest songs I've acquired are at the end. . %last_modified% is close but not quite because if I edit the tags it messes up the sort.
I know there is a plugin that lets you write a created tag to the song. But that seems like unnecessary complications; it also messes up last modified, which I may need for other programs. Seems like it'd be simpler and more straightforward if there's a %date_created% field. I think that can be read from win32 api right?
A related question: is it possible to group first, then sort, rather than sort, then group. The reason: as I mentioned, I sort by %last_modified% and group by %album%. The problem here is if I edit the tag of one song, it now sits in a group by itself, because it's much newer than the other songs in the album. The workaround is to use 'touch' to modify the dates of the other songs in the album. I'd much prefer to group first, then sort by, say, the date of first song in the group.
I am using columns UI and elplaylist, if that matters.
