As you would expect, this takes memorable songs from classic Famicom games and gives them a reggae flavor, though they still retain a bit of their chiptune sound as well, it seems. As you would also expect, the one Mega Man-themed track on this album is Rockman 2's Wily Stage theme 1. I think it's a law that any game album featuring Mega Man music requires that track. You can sample it in the above preview video at the 1:38 mark.
