Jumping Flash!2 Original Game Soundtrack contains songs from both JF!1 and its sequel. Unfortunately, some of the songs from each game have been left out, so the soundtrack is not complete. However, most of what *is* included is certainly good enough to jump around to.
The songs are all OSV with the exception of a Techno Mix of "Rap La Muu Muu", the ending track from JF!2. My personal favorites are "Slippery Ice Land" (ever heard a thumping bass and a cello section combined?), "Distant Cosmos" (Papa's got a brand new funk!), "Transforming Cube Machine" (killer boss music), "Aloha Robo" (Falcom-esque power rock), "Jump In Hawaii!" (a little milder, but great ukulele), and "Aloha's Secret Base" (a brutal rhythm and industrial melody make this the most "grown-up" track on the CD). There's also the hilarious "Rap La Muu Muu" (performed in Japanese) which, surprisingly, remained intact for the American release of the game.
While most of the songs here are undeniably bouncy and childish in nature, they are certainly well-composed and provide a nice contrast to other more popular game soundtracks.
