Reading your answer to kelly's question and her suggestions, I think u should listen to "baladas pop", unfortunately I don't like this genre so I cannot recommend u particular songs but I know some mexican bands whose songs are this type, u should listen to "Camila" or "Sin bandera", they have plenty of slow songs according to your likes.

Antonio José "El arte de vivir", " De que manera"... Malú "Blanco y negro", " Ahora tú".. Melendi " La promesa", " Con solo una sonrisa" Pablo Alborán "Solo tu", " Quien"... Lagarto amarillo "Culpable" Felipe Santos "Olvidarte" Dani Martin "Emocional", "Cero"... Leiva " Terriblemente cruel" Extremoduro " Si te vas" XRIZ " Mienteme"

There is plenty of beautiful music in Spanish... it depends on what kind of music do you like!. Do you have any favorite music gender? :)
