User:Kuno/Recording Suggestions
There are several different scenarios the Recordings tab has to deal with. In this document I try to describe what the tab should be doing in each situation.
Tracklist level
When adding a release or medium the supplied tracklist is compared against existing tracklist.
| Scenario | Action | Confirmation | Implement |
|---|---|---|---|
| The supplied tracklist is identical (or identical with only case changes) to a tracklist in the database. | Recording suggestions are taken from the existing tracklist, no other suggestions are offered. | not required | NGS |
| The supplied tracklist is similar (case/punctuation changes, possibly other small changes calculated with some distance algorithm) to a tracklist in the database. | Recording suggestions are taken from the existing tracklist, no other suggestions are offered, confirmation is required for the tracklist as a whole. | required | Post-NGS |
| The supplied tracklist is identical to the first X tracks of some other tracklist. Presumably the existing tracklist has bonus tracks, false positives would be likely with a limited number of tracks so this match should not be attempted for short tracklists. | Recording suggestions are taken from the existing tracklist, no other suggestions are offered. | required | Post-NGS |

Any confirmation prompts should be a single prompt for the entire tracklist.
Track level
NOTE: the following should all be implemented in NGS. Most of this should have been fixed as part of MBS-1515.
New track has exactly one identical recording
Description: When adding a track the new track title + artist preview combination has one exact recording title + artist preview match in the database.
Action: Suggest the recording, no other suggestions are offered, confirmation is not required for this track.
New track has exactly one similar recording
Description: When adding a track the new track title + artist preview combination has exactly one similar recording title + artist preview match (case and puncturation changes allowed).
Action: Suggest the recording, no other suggestions are offered, confirmation is required.
New track has several identical recordings
Description: When adding a track the new track.
