It may be because I tend to listen at low volumes. When I got my first ipod, my dad wanted to check how loud it was, and he believed I had lowered the volume before giving it to him. I might edit levels and frequencies later, as I haven't mastered/mixed it at all pretty much. (I've been lazy)
Nice one. I think the synths may be too loud in places though. The high notes sometimes hurt my ears. This is a really cool track though. I've probably just got over sensitive hearing.
