I first heard it two days ago and haven't stopped since. I'm not a music expert, so I won't comment the technicalities, but I can tell you this: it's a fresh, up-lifting and mood-elevating work of art. I love it.
Too bad I can't understand much of the text since I don't speak Spanish.
Just one thing: There seems to be something wrong with one of the songs (it stops playing in the middle of the song), I think it was Vamos Todos, but I'm not sure. Anyway, you might want to check that out.
