Hi!
I recommend you the Strings and Piano version of 'Pingüinos en la cama' by Ricardo Arjona. It's awesome and I think the piano is quite easy. That's all I can tell about Latin American music, which I don't know very fine.
However, I can recommend a lot of things of Spanish music:
- '¿Y si fuera ella?' by Alejandro Sanz. It's very very known here.
- 'El Último Vals' and 'Dulce Locura' by La Oreja de Van Gogh. It was released this year.
- 'No me importa nada' by Luz Casal.
- 'Estoy'. I'm not sure about the composer, because it's been sang in Operación Triunfo (a talent show) by some cute boy called Iván. Search 'estoy ivan ot'. This song is really beautiful.
I hope it's been helpful.
Bye!
