out of couriosity , any video or audio examples of this?
My local events don't get filmed. There is a small number of 'salsa' nights that feature large quantities of (so-called) r'n'b, where people dance salsa to non-Latin music. I have already had requests for footage of this phenomenon, but unfortunately none exists, although these nights are very popular and have been running for years. Then there's the more typical salsa nights, where it's not unknown for an r'n'b tune to get dropped in the middle of some salsa, whilst everyone continues doing the same moves they always do.
The worst example of this is the tune by Sergio Mendes with Black Eyed Peas - I don't know what it's called, nor do I care, but it's not salsa and I've heard it hundreds of times. It is a good tempo to dance salsa to, but it's not salsa. It packs the floor. What is wrong with these people?
What's more common is Latin r'n'b tunes(salsaton or similar), because they remind people of the music they actually like i.e. r'n'b. A lot of DJs and instructors - even the better instructors - love any Latin r'n'b type tune that is the right tempo for salsa (or cha cha), and use them in the lessons. I once went to a lesson where we were taught a very hard shine routine, then had to practise it to R&B Latino by A Wilson; as well as not being the real deal, it is far too fast to practise a new and hard pattern. But because it's r'n'b style, it's considered better than the real deal.
I'd sooner hear reggaeton or kuduro at a salsa event than this r'n'b crap - at least when reggaeton or kuduro comes on, people don't dance salsa.
I won't go to most events in my locality. Fortunately there are a small number of really good nights, where I can treat my ears and get lots of good dances.
