Two normalisation faults, both found by running a real coverage report's unmatched list back through the normaliser. Between them they account for five of the fifteen worst misses by play count. The guest-credit pattern required whitespace immediately before the word, so it caught "Yellowcard feat. Tay Jardine" but missed "Self vs Self (feat. In Flames)" -- and the bracketed form is the more common of the two. An opening bracket is now allowed in that position. The trailing-version pattern matched the suffix as a run of non-hyphens, which cannot cross a hyphen inside the suffix itself: "Gold Dust - Shy FX Re-Edit" and "Back To Your Roots - Friction & K-Tee Remix" both survived untouched. Matched lazily instead. Four version words are added for how drum and bass marks its variants: vip, bootleg, rework, extended. They only apply inside a bracket or after a trailing dash, so the exposure is small, and ordinary titles carrying those words -- Editors, Mixed Emotions, Radio Ga Ga, Live and Let Die -- are pinned as tests against exactly that. The report also gains the figures that explain why the MBID tier contributes so little. Two thirds of scrobbles carry a recording id, and only a twentieth of them join on one: MusicBrainz holds a separate recording per release, and the two sides rarely choose the same one. Counting the pairs that carried an id and matched on name anyway measures that disagreement directly, and settles that the weakness is not a bug in the join.
