These were very safe bets but
this album is confirming a few songs credits from Sword and Shield :
Go Ichinose :
-
Battle! (Wild Pokémon)
-
Battle! (Trainer)
Minako Adachi :
-
Battle! (Gym Leader)
EDIT : also, Game Freak/TPCI, now that all the DLC are released, please give us the Pokémon Sword and Shield Super Music Collection (and including Ultra Sun and Ultra Moon music would also be really cool).
