Seven minute pregap on disc 1 track 4 of https://vgmdb.net/album/5549 , it's a whole long discussion between songs, with some audience cheering. VGMdb follows the "append pregap to previous track" convention, that's why track 3 looks so long. There's similar but shorter gaps with banter on tracks 2 and 7.

Cuesheet looks like:

    TRACK 04 AUDIO
      INDEX 00 00:00:00
      INDEX 01 07:34:43

Edit: Probably covered by your sfx disc, but this one has 17 indexes on track 1: https://vgmdb.net/album/3091

That messed with a tool that only anticipated one index in track 1 for detecting hidden pregap audio, cuesheet is like:

    TRACK 01 AUDIO
      INDEX 00 00:00:00
      INDEX 01 00:00:37
      INDEX 02 00:11:40
      INDEX 03 00:37:33
      ...
