Apparently (as I've never been to an actual Hillary rally) this is the song they use when she gets on stage. It's from a Dutch band called Golden Earring and the video clip of this song is the first music video ever to be banned from MTV.
It shows the leadsinger raping two women (one of whom is a nun) and human tissue being fed to a dog. It's way less gruesome than it sounds though.
Btw. Bill used the song 'Radar Love' from the Golden Earring during his 1992 campaign.
So that concludes your quick history lesson for today lol.
