Very good, but it has some issues. For one, it should have been longer. If you make a dance song, or dance-like song, you should give the dancer plenty of time to wear themselves out. There was a spot around 45 where you put the melody in the back and threw the techno in our faces. That was alright, but I had to try to hear the melody. It should have been a bit more present. I also noticed that the dynamics almost never changed. You might fade something in or out, or even drop it altogether, but the song never changes. And remember when your English teachers back in elementary school told you to write a conclusion that was similar to your introduction, but still different? You can do that with music too. Instead, you just dropped the entire song all at once. If nothing else, you could do an echo effect with the last note.
By the way, I only gave you a four because I know you can do better. I know this is an old song, but hey. Maybe you read these anyway.
