i think there is a solution for this problem
even tho i put up "sand" on youtube as it is since it has been an inside joke/meme in xG TF2 JB since ~2013, i do agree that putting distorted music in a map wouldnt be the best idea
although i also do believe that xG memes should be included in the map so i would suggest adding it as the non-distorted version
most preferabbly in a very secret area/noclip only area, where it can only be heard there (unless more people want it to be put the original way, which im also fine with)
here's the original source of "sand"
