Well a lot of people in their early 20s aren't necessarily set in their ways. That is a pretty significant part of Bad Bunny's fanbase, and an age demographic that salsa has struggled to recruit from in recent years.Regarding the current topic in this thread: does playing a salsa song at the Superbowl halftime show have much effect on the growth/decline/ evolution of salsa?
Hard to say but I would guess no. People who are adults and are or would be new to salsa are going to have music preferences already. If salsa is not their current preference, why would that change because of one 13 min show on tv?
As to the effect on people who already like salsa music and dance to it or for whom salsa is part of the culture? It is kind of a validation to see the music one likes, dances to, or is a part of culturally to be performed in the mainstream. It does not get more mainstream than the Superbowl. The show does not have to be good. The song does not have to be good. That is not important. What is important is that others notice that this is part of a culture not just mere entertainment.
Even later on when you're older... I didn't really consider or listen to salsa as a genre until social media randomly recommended back to back videos of ETJr dancing w/ Veronica Lopez to Regresa by Alvaro del Castillo, and then Milton Cobo dancing with Isabel Freiberger to Via by Al De Lory. I was in my 30s when that happened. That's all it took for me - two back to back videos and I was hooked on the music, and started taking classes a couple weeks later.
