I realize this is super specific, but I guess thats why we send in reports!
When getting a track listing via discogs where an individual track is split up into sub-tracks, the information is displayed as if they are individual tracks which messes up the numbering.
Example: https://www.discogs.com/Joris-Voorn-Fuse-Presents-Joris-Voorn/release/531521 has three songs under track 3, two under track 4 and three under track 5 which makes eight songs altogether. However one would presume that in actuality there would only be three files reflected.
Of course, there is no standard as to how these tracks are to be denoted within Discogs (the closest they come is "Use a Logical Scheme" https://support.discogs.com/hc/en-us/articles/360005055373-Database-Guidelines-12-Tracklisting#Megamixes_And_Medleys here.
My suggestion is more generically to be able to combine tracks fetched via external databases into a single track with the information merged into each field with a user-selected separator (perhaps a "/" by default?)
Anyway niche case I know but I thought i would bring it up as it probably happens from other sources as well.
