Well, since Persona is anime now, I can introduce you to the music of the talented Shoji Meguro. His signature style of rock mixed with various genres such as hip hop, electronica and RnB has appeared in many titles of the Megami Tensei series of games. It is no surprise then that he returns to compose the OP and ED of the Persona 4 anime, which is currently airing.
I usually don’t go for poppy songs, but theres just something so catchy about his upbeat tunes, with contributions from Lotus Juice who worked on music for Soul Eater and Katanagatari, as well as Shihoko Hirata singing the oddly endearing engrish lyrics. Meguro also composes orchestral peices for the soundtracks.
On the whole I think I enjoyed the OST to Persona 3 more than Persona 4, though I attribute this to the fact that Persona 3 songs seem to stand on their own fairly well (and who could forget the BABY BABY battle theme), though both soundtracks compliment their respective games fantastically.
