The person below me has a point. It's a bit too loud for me as well, and I tried turning down my volume. Maybe your sound device makes it so that it doesn't seem too loud to you. (Headphones vary in sound quality).
I would try testing your song out on at least 2 types of headphones and 1 speaker with a subwoofer function-- such as a decent quality car stereo or, in my case, I use a logitech black speaker set with a subwoofer that allows me to hear bass and treble volumes.
This song is actually pretty good, I enjoyed the keys that went on throughout the song. Just work on your volume
