Wow, guys. I'm Mexican and not a fan of Bad Bunny at all, but you seem really out of the loop with this guy.
He is a Puerto Rican, and in that sense he is an American citizen, but Bad Bunny is a sovereignist that would very much prefer to be free from the USA. The song Ricky Martin sang during the SB halftime show is just beautiful (listen to the Tiny desk version!). The name of the song is "Lo que le pasó a Hawaii" (What happened to Hawaii) and the lyrics talk about a strong, deep feeling of belonging to the Puerto Rico island. He talks a lot about the simple life in there and some of their traditions. In the end, the song calls Puerto Ricans to hold their flag and don't allow "them" to do to Puerto Rico what happened to Hawaii.
I was in awe to listen to at least some of these lines in the middle of the Super Bowl. Honestly, don't even try to ask me about the rest of the show.
