Agree with all of the rest above. Why care whether it is known, overplayed, or never heard before, is it if inspiring enough to keep you on the dance floor.
Last week’s social (newly started), for first hour and half played a lot of Timba. I don’t know if you would fall into timba-son category, but it was the type of timba that was you could easily dance salsa too. The people dancing were 100% salsa. The DJ playing only DJs at the salsa events, not timba events. Our DJs do occasionally play timba that can be danced to at exclusive on2 events. There many beginner level salsa ladies and most were struggling to dance to the timba. To me from the sound, it felt timba though I had not heard most of it before. It was still very danceable. I would have preferred to dance it with better dancers who would interpret all the interesting percussion rhythms. I felt odd that the DJ was playing so much of timba sound. Some regulars wondered what he was playing and I told them it is timba.
After the dancing when we were eating out a couple of other DJs confirmed he was playing timba. The guy who hosted the social and is a on2 dancer, said he asked the DJ to play timba. He wanted the event to attract the the timba crowd. Which is a lot smaller than salsa and mambo crowd. The others including DJs who have been on the scene tried to explain to him it has never worked in the scene for the last 20-30 years. I personally know several attempts by enthusiastic dancers trying to play to both salsa and timba crowd at both events in 2000s. Both groups hated the format and attendance dropped after the opening weeks. The guy has his own wrapped view. He claimed he saw some timberos in the crowd. The rest of us told him that no one was dancing timba on the floor. He continued to claim there were timberas in the crowd. We do have a few followers who dance both timba and on2. They are regulars at the mambo events and also at timba events from what I can tell. But I saw only one regular in the crowd that night. DJ being salsa DJ knew what kind of timba to play for the salsa crowd where I think most people didn’t realize he was playing it.
Regarding overplayed music. If I really like the song, it is like comfort food. It I don’t have strong liking or disliking, it can be irritating. Like “ain’t no sunshine”, it gets played almost every single time I go out dancing. I like the music orchestration in it but the moment the vocals kick in I dislike it. I think that’s because the vocals don’t have the salsa singing feel to it.
