Yakuza Kiwami 2 (#9577)

[Enja Hamman]

ZENTA adds a lot of his Like a Dragon songs to JASRAC way before there's any album releases, so that helps with Kiwami 2 where we still haven't got one yet. These are the ones he did.

マジザコ戦 | MAJI ZAKOSEN | Majizako Fight (community name seems to be Sins of the Father)
闘技場：バトルロイヤル | TOUGIJOU BATORU ROIYARU | Arena: Battle Royal (community name seems to be Eight Man Brawl)
クラン汎用ＢＴＬ | KURAN HANYOU BTL| Clan Generic BTL (community name seems to be Defend Your Property!)
クランボス戦 | KURAN BOSU SEN | Clan Boss Fight (community name seems to be Demolishers)
TOWN BULLY (reused from Yakuza 6?)

I think basically all of these songs, the community thought Chihiro Aoki was the most likely to have composed.

Not that it narrows things down a lot, but Hyd Lunch confirmed that Matsuzaki played instruments on the karaoke song Pride From Despair (絶望頂プライド), plus some other karaoke songs and battle themes.
