I was bored and since everyone compares Rolando to Loco Roco I took the music from LR and played it while Rolando was playing. The style certainly seems to fit with Rolando. http://www.youtube.com/watch?v=MRC39xfWi4c
I agree, having owned both the similarities lye only within the design and cuter elements of the game. But not much within the gameplay aspects, so I threw the music in there to see what it would be like.
