Great song, and I like the overall balance of frequencies (didn't find it fatiguing or anything like that), but when I listened to it again, this time on headphones, I'm sensing something not quite right with the stereo image...I'm somewhat of a n00b at audio so I don't really know how to describe what's going on in technical terms, but it seems like something is going on in the high frequencies on the left side, as if they're pumping in and out a little, making the stereo image feel somewhat unbalanced. The closest comparison I can think of is in the first Ryko release of Zappa's "You Are What You Is" CD, which had problems with the mastering. On Wikipedia it says the problem was caused by "an overuse of digital techniques like compression and reverb." It's not as pronounced as on the Zappa CD (which seriously caused my eyes to water when I listened to it on cans).
Again I really have no idea what I'm talking about, and maybe someone more knowledgeable than me could chime in hear by giving it a listen on cans, because perhaps I'm just too tired or something

but my left ear did feel a little left out, is about as technical as I can put it....
Otherwise a great song, really enjoyed this.
