Absolutely wonderful work! The tracks jive together to form a cohesive whole while each bringing their own unique flavour. You've done a great job of conveying a sense of the time pressure, too. Also loved that you included a "game over" and "try again" track - I can totally imagine this being a fully fledged game! Catchy, high quality stuff. "Pop Concert" was my personal favourite for the sound choices you made. :)
