I've been tagging some releases in this series. Most of the titles as I have them are just "Cold Hands Seduction Vol. ##". Using lookup in Picard almost never finds anything. Even Lookup in Browser almost never finds anything.

After trying some different things with the fields from Lookup in Browser, it seems like "Sonic Seducer: Cold Hands Seduction" by itself will return all of the releases in the series, and even just "Cold Hands Seduction" returns mainly those. But as soon as you add "Vol." or "Volume" anything, unless it's formatted EXACTLY as in MusicBrainz, it doesn't find anything from this series. And when it is formatted the same, it finds ONLY that release, nothing else from the series. Very strange.
