When deleting a disk ID, a warning is displayed that “a release can have multiple valid disc IDs”. How different may be different disk IDs attached to a release?
Here is an example I encountered today: CD 7 of the release https://musicbrainz.org/release/a830f892-6be0-35f0-a392-b91d89d89a94/discids
This disk ID has been attached to the CD before: https://musicbrainz.org/cdtoc/A7ZO3ZuXOWVlCtfY6_XXnyTtzxI-
This disk ID was calculated by Picard from a physical CD I own: https://musicbrainz.org/cdtoc/ulTFdtc0WHDnrvh_lRunGfdYGk4-
Track durations on two disk IDs are very different. For example, track #2 on the “old” disk ID is 3:49, on the “new” 2:51. There probably could be some explanation when track length differs for a couple of seconds, but here the difference is nearly 1 minute.
The length of the track #2 printed on the CD cover is 2:51, the same as in the “new” disk ID.
The “new” disk ID also matches with two other releases of the same work, links are available from the “new” disk ID.
Is it safe to assume that the “old” disk ID is wrongly attached to the release and remove it, or is there any legitimate scenario when a release can have valid disk IDs with so different track lengths?
