CyList is a site where people can make lists of anything. Much of the content seems to be CD track listings. Very bare bones numbered lists but it’d be better than a folder full of tracks with no tags at all. Definitely would beat typing in or copying and pasting.
Here’s an example George Jones: Classic Country CD Track Listing at cyList
Ignore the cruft and scrape the numbered list for data. Looking at several lists they mostly are
Track number. Artist - Track Name (duration)
- GARY - Angel. (05:16)
Some are
Track number. Artist - Track number - Track Name (duration)
GARY - 01 - Angel. (05:16)
May or may not be a . after the Track Name. May not have (duration). But at the minimum there’s the track number and the name which if one knows the album title and artist but not the track names and it’s not in Musicbrainz or Discogs, at least you’d have the names.
CyList is the only place I’ve found track listings for Digital Juice BackTraxx music library and their other products.
