Russian song at romance festival

I went to the romance festival with my Sims tonight and a Russian song was playing? Not in simlish, a Russian song is Russian, it was Хулиган by ганвест, it was kiindd of popular in Russia about 2 years ago?

I have mods, but I don't think I have a music on eor something... Did anybody else see this? The song is kind of inappropriate (foul language and all). Was this actually added to the game or is it a weird mod I forgot about?
