If metadata for a new release are uploaded to MusicBrainz, please use the AcousticID at first for the suggestions on the Add Release -> Recordings tab for recordings, which are already registered in MB. The are too many false "track - recording", when only artist, title or track-length (+-5sec ?) matches.
Think of all the rehearsals an artist does, where the title is the same and the track-lenght is about the same.
