Several YouTube Music URLs that should use music.youtube.com were entered using www.youtube.com instead. Presumably due to overzealous YouTube URL clean-up:

• https://tickets.metabrainz.org/browse/MBS-10226
• https://tickets.metabrainz.org/browse/MBS-11556

Examples:

• https://musicbrainz.org/search/edits?conditions.0.args.0=90024290&conditions.0.field=id&conditions.0.args.1=90024291&conditions.0.operator=BETWEEN
• https://musicbrainz.org/search/edits?conditions.0.args.0=90024394&conditions.0.operator=BETWEEN&conditions.0.field=id&conditions.0.args.1=90024395
• https://musicbrainz.org/edit/90024638
  These can't be updated without following a "redirect". Unfortunately this requires to parse the HTML response unless the YouTube Music API is used in some way.
  In script tag, search for:

  [...]
  initialData.push({
                      path: '\/browse',
  [...]
  

  Parse data to find:

  {
      "microformatDataRenderer": {
          "urlCanonical": "https://music.youtube.com/playlist?list=OLAK5uy_k6ICDchO9n37IfEc_LuLwZYdUvywQqoUM"
      }
  }
  

Playlist IDs starting with OLAK5uy_ are YouTube Music albums that would map to a MB release.

YouTube Music URL relationships should also be changed to actually use the YouTube Music relationship type.
