Well, I know how some people feel about conversions, but I'd recommend DLing the wav and converting it to a high quality mp3 file yourself, then deleting the original wav. Or downloading it and burning the wav directly to an audio CD, which would be even better, if you were making such a remix CD. That clears the problem up, and plus you get a better sounding mix of the track.
I can understand not wanting to download it, but unless you literally don't have 74 open megs, it's your best bet.
I don't know, maybe it's just me but I loved it from the start. Especially the scream effect, that perfectly brought in the classic kind of spooky ambience that Metroid has.
By the time the jazz section and other parts came in, I was too into it to think it may have seemed strange.
