Dripping with Style
From Inkipedia, the Splatoon wiki
Dripping with Style is the song played in all of the shops in Splatsville. It plays in all five, with each having a remix of the other. These are not specifically named. The jukebox plays only one version: the Ammo Knights version. It is the only song/music known to be created by Seven Seas Crew. It does not resemble Lookin' Fresh, the music played in Inkopolis shops, nor New You, the Inkopolis Square shop music, which are known to resemble each other.
