Well, you won the jackpot. 2 and a half months of non-stop exposure. If the buyers don’t want to buy that track, well, that’s another story… 
I would probably change the icon to your regular logo, however, for brand recognition.
Also, many buyers don’t immediately buy what they find. They might put it in a collection and a few days, or weeks, later, when they DO need the tracks, you might see a bunch of sales.
