Aandrew even though certain music themes play for other Large Monsters they're attributed to or made after certain monsters. For example one of the old Desert Battle Themes (can't remember which one) were themed after Monoblos, the Forest and Hills Battle Theme's made for Rathalos, IIRC the Old Jungle theme's for Rathian, MH3's Volcano was made for Agnaktor, and Tundra's theme was made for Barioth.

Anyone is free to correct me if I'm wrong on things but that's from what I can remember.
