The reason why this song received a 3.75 is because people vote 0 on songs for no good reason.
It is a very happy song. It made me feel happy too. I thought the bass was very repetitive, im glad you stopped it for a little at around 2:09. I also didn't like the sound of the bass, but that's just my opinion. I liked the sound of all your other instruments though. I didn't like the ending. The bass and drum beat just stops so suddenly into the main melody and there isn't even a fade out. You also didn't give the song enough time for the delay/reverb to end on the last note.
