When my son's class at school were aged 7, this was the end of a 'cycle' of primary education here in Spain, and so they had a kind of mini-graduation ceremony, which involved them performing a dance number.
They had been asked to choose the music, and the most vocal group wanted it to be hip-hop. The teacher was a little unsure, but they ended up selecting Macklemore's Thrift Shop.
Given their rudimentary English language skills I think that both the bleepable-for-radio language, and sadly its excellent anti-consumerist message, passed them all by. There was definitely no singing along.
