What is this about el matador?

I think it is for El Matador but i don't know cause El Matador did play in Arjentina with Boca and maybe the band made a song for him but i don't know. lots of bands make songs for famous people. they made some for Cristiano Ronaldo "Ronaldo eres una Barcbie" not a fmous song but it is sung by the fans. And they also made a song for wila13 its called "Puto" from molotov !!
