I have agree and disagree to the post above. Yes it is easier to recognize a song through the singer,
but the more you listen to timba, the more you recognize the song by it's
style.
Formell, Manolito, Pupy, Limonta, Calzado, Valdez, Blanco.. etc. they all have their own unique style of making music. I notice that it is rather easy for me to recognize a song by Formell, despite who the singer is. In the older songs you can always hear if Pupy is playing the piano. It always depends on the song, but usually each song has it's trademark - for my ear atleast.
Same goes for Bamboleo, especially with the trumpets. 5 seconds and you know it's Bamboleo.
Of course here, especially in the older songs, I can't tell if the song is made by Limonta or Lazarito. But you can hear it's Bamboleo for sure. Azucar Negra and Limonta together are maybe a little bit harder, Calzado is way too easy. I don't even know CH singers but I can spot a CH song like that. I bet everyone can. Manolito, Maikel Blanco, Reve - same thing. Well especially Reve, but this is because of his changui influence I would say..
Maybe the only one whose style I can't recognize easily (from the great ones) is Adalberto. Solo artists are little bit different, but even Paulito - even though he sings - has his own style in his songs.

Now I'm not saying I can spot every single song - that's impossible

Yes it is easier to recognize the song through the singer, but sometimes you don't need to hear who is singing .
