YES!
dude! amazing! that was absolutely excellent. everything about this was just really damn good. there have been people who tried to make music-making games before, but this is only one of two (punk-o-matic) that i feel actually do a good job. thats only the ones ive seen of course.
so a quick, although rather unnecessary, breakdown. the graphics were, as you said, visually appealing and calming. they were a perfect match for the style of music you included and just worked well. style, earned you a perfect score because of the way you put it all together and cranked out an excellent piece of work. music was genius. a combination of simple and complex rhythms and beats, but when you put them together some really amazing songs come out. and the quality was top-notch, by the way. interactivity gets an easy ten also.
i do have one criticism, but not to you. the first reviewer is so full of shit. crooked text? actually it isnt. its slanted to match the page that comes out from the side (another characteristic i liked). so that idiot needs to shut his mouth and leave because he decided to vote zero for a shallow reason and obviously never even played the game. people like that just suck.
so a score for you: 10/10 and 5/5. lookin for this to be on the front page and get a great score. well, that and for you to make another with a different song :P i loved it. keep up the great work.
