Have a musical day

Watching Ice Dance at the Sochi Winter Olympics this morning, I'm wondering how or if the choice of music affects the judges' perception.  The competitors were dancing to older tunes this morning - not a bar of Eminem to be heard - but some tunes were more familiar than others - and definitely more upbeat and fun.  Did the judges think so as well?  Or are they trained not to take any notice?  I know that as the competitors danced, I was bopping along with some of the music in my head and thought those with the "best" music had done better - and the judges seemed to think so as well!  Or perhaps they were just better skaters. Hmmm.
