a parking attendant, an Audi, and Russian hip hop

What do these three things have in common?  I rode to the city in an Audi with a Russian (I think that's what he was) parking attendant listening to Russian (I think that's what it was) hip hop.  It was a very odd experience and one of the two strangest I have had with Casual Carpool.  As I got into the car near Lake Merritt I wondered why was there a early 20s East European kid driving around a rather nice Audi.  My curiosity was immediately peaked when I saw that he was wearing a jacket from a parking garage management company.  As Occam's Razor will show I'm sure there was a better explanation, but the gears started turning and I wondered whether this was even his car.  I figured if I carjacked a car then the last thing I would do is go pick up a bunch of Financial District suits first thing in the morning and take them to San Francisco.  Anyways while we were driving along listening to Russian hip hop a song came on.  I knew the beat, but the lyrics were in another language.  However, I swear that I heard a Russian version of this song.
