Omg Guachineo was all the rage in Cuba when I was there in March and April!! Such a fun song to dance to, even for non-reggaeton fans like me By the time I got back to Cuba in June, there was no Guachineo to be heard anywhere, guess there are so many reggaeton bands that they move on quickly
I'll start with an update from a friend of mine who got back 2 weeks ago.
1. La Gozadera - Gente D'Zona, Marc Anthony (unchallenged in first place)
[MA is always #1 in Cuba with whatever song it happens to be at the moment]
2. All the songs from Los 4 latest album
[Privilegio @ Sptify : https://open.spotify.com/album/1pbwGGFnRCn3OK52xIzUGf]
3. Desiguales - Eso es bola
In terms of salsa/timba - Havana D'Primera and El Niño y La Verdad are big.
