Very catchy and fun to listen tune. I love the simplicity of it and the fact that failing a section does not send you back to the beginning. I did want to suggest that the some the "listen" parts where a little long and I wanted to start tapping to the beat but would lose the because there was no markers. lol.
Also, it would be great if of the sustained notes such as with the brass segments we would have to hold down the button for as long as the note is sustained. :D That would add that extra funness to the game. Overall, well done :)
