682-00052: serani poji special remix

[Chris Porter]

On the back of the Playstation 2 game box it says: 音楽プロデュース：福富幸宏（ＤＪ／アーティスト）.

That's Yukihiro Fukutomi (https://vgmdb.net/artist/8104). Should I put him as the composer of the original tracks? Or are the tracks that are remixed on this CD different from the music that Yukihiro Fukutomi was responsible for? I know that the group Serani Poji was created to be the in-game band that the main character Neji Taihei listened to all the time. Does anyone know if Fukutomi was responsible for those compositions as well?
