In this interview a member of the group says that they don't have a release date yet, but it will be soon. http://www.publimetro.co/entretenimiento/bomba-estereo-ahora-rapea-con-will-smith/lmkojh!Jcim3aPhaCqZ/
Welcome to the board! Well, I don't know the title of the beat from the video you posted, but, if I'm not wrong, I think it's fake, meaning that someone made it for the video but it's not the one from the Spanish version. I'm Spanish and I remember the same exact beat from the American version being broadcasted here. Next time I watch this episode I'll pay attention to this scene though, but I doubt the beat is different from the original version. Why would they do that, anyway? Good luck with your search, and welcome again!!
DJ Jazzy Jeff on possible reunion with Will Smith: 'The time is right on so many different levels' "I've been waiting for him just to say, 'Let's go,'" he tells EW. http://www.ew.com/article/2015/10/07/dj-jazzy-jeff-reunion-will-smith
Hmmm.. I'm not so sure about that. A few years ago Will said "I'm done with music", and later we found out it was Jaden the one who had told him to stop rapping. Plus, to be honest, I wouldn't like to see the Smith kids involved in this. I don't mind JJFP performing with other rappers, but at the end of the day I only want to see Will and Jeff on stage.
