I don't see what the big deal is here, really. It's essentially the same thing as telling the online community where they can hear the song on radioplay (like the original poster has done.)
Instaed of looking for it, well, "gunhaver" just made things easier I guess. Gives us a nice taste - and a taste it all really is. Hell, we have some idea of the song, but blasting it out loud on your speaker system with ultra-crisp sound will be a whole different story. Pure...and...simple.
Like, if THE MOOR was in this quality, we'd hear some nice stuff, but geez, it sounds SO DAMN GOOD on a nice pair of JBL speakers, oh yeah (and right off the album itself, of course.)
