Is Brazil's Ronaldinho one of the best soccer players of this generation? Sure. Is a he a great singer? Eh, he's decent, but it's debatable if he's good enough to make a full World Cup anthem like he tries to here. Ronaldinho teamed up with rapping friend Edcity to release "Vai na fe," translated as "Go in Faith." The video is complete with scenes of Ronaldinho playing soccer and kids doing the Sambaâ€”because Ronaldinho is about the kids. Those kids are probably not going to be too happy if Brazil ends the summer with anything less than a World Cup, though.
