Have heard "Rolling Doubles" a hundred thousand times. Used to put it on in the background while I was grinding in WoW, circa 2008-2009. Since I couldn't be bothered to minimize and change the music, it would play over and over again, for hours. I never got sick of it. To this day, I will occasionally remember it exists and put it on in the background while I work or play games.
I don't remember where I bought it last time (and the download is long lost) so I bought it again here on Bandcamp.
