Also, and I've seen this with other programs done by non-native English speakers, I wonder have much of the lyrics they understood. The impression I had in the interviews I heard was they liked the beat and the music, not that they understood the meaning of the lyrics. I can certainly remember several instances over the past few years, which ice dance team was it that skated to the song about a mass killing, where I was pretty sure (based on choreography and facial expression) that the skater/skaters had no clue what they were skating to or the historical context of the song (Sixteen tons) and really needed someone to translate the lyrics.
