4 Plugs is the sixth album by the Mad Capsule Markets.
The album has been known as a turning point in the band's career as it was a departure from the original melodic Japanese rock and punk sound to a more rap metal-based style.
The melodious elements heard on Mix-ism and Park are largely gone, the sole exception being "Normal Life", replaced by aggressive and heavy beats.
Most fans welcomed this newer sound and style, and the band attracted a new fanbase, but some fans of their earlier sound felt disappointed with their new direction.
[1][2][3][4] This album also featured almost fully English songs such as "Walk!"
