I tested the Alkaline album, the main problem with it is that on Discogs it has no track duration, so to reiterate in order for Jaikoz to match a particular song from a discogs release to one of your songs the match has to be made on either TITLE, TRACKNO or DURATION.
So it can’t match on duration because Discogs does have the duration. If the Title is blank it cant match on that either, and if Track no is blank as well then it cannot do any match.
You can test this out, if you manually enter the Track No for each track in the track field as a single contiguous number 01,02…27 and run Update Tags from Discogs it should fill in the missing track info.
But as I said before there is a bug with not taking Disc No into account so if you entered the tracks as 1-13 and Disc No 1 , then tracks 1-14 and Disc No 2 it will only correct tracks 1-13
