If you don't have a strong comprehension of salsa music you are only dancing to one layer. And there are many...most having to do with the music. So I can for sure say that people who are not into the music do not dance as well, in salsa that is. They might me able to dance well technically but there is a disconnect. Therefore they will lack "sabor". Is the enjoyment at a different level? I would say yes. They might enjoy the dancing but if they don't enjoy the music they are only getting half of the experience.
