Hi, received the support files, the issue is that your track 6 is not being matched to the MusicBrainz track because the track lengths do not match up, your track is 33 seconds longer than the time registered on MusicBrainz
For your typical 4 minute pop-rock track this is a massive difference and indicates an error, however for a 17 minute track the difference is less problematic. So maybe the track duration check should be proportional rather than hard coded limit of 10 seconds
Checking Release Track Duration Failed:Igor Stravinsky, Bergen Filharmoniske Orkester, Andrew Litton:10934884:The Rite Of Spring; Petrushka (1911):Song:Le Sacre du printemps:Pt. II: The Sacrifice:1105:Seconde Partie: Le Sacrifice:1072
You may be able to override this in the forthcoming release which contains a Match to One Album task, expect to be done this week.
