While entering tracklists in MusicBrainz, there is a length field for each track. This field is not parsed appropriately when colon separator ":" is missing. Instead of considering a number of seconds, the parser should insert colons at appropriate places.

To complete the task, submit a pull request to our GitHub repository with a proper description mentioning the linked ticket, and respond to any suggestions and requests by the MusicBrainz developers until the pull request is approved (you do not need to wait until it gets merged).
