Prende comes from the verb prender, which literally means "to turn on" or "to light up", like a light switch or a fire.
In many Latin American countries, it's also popular slang for something that excites you or gets you hyped up. When the song says "esta música sabrosa que me prende", it means "this delicious music that gets me going" — capturing that feeling when a great song comes on and fills you with energy!
This song is a straight-up command to get on the dance floor! Deorro and Elvis Crespo aren't asking, they're telling you, "Vamo a bailar" [Let's go dance]. The whole track is built around the energy of a party just getting started. The lyrics say, "La noche comenzando / Y el whisky calentando" [The night is starting / And the whiskey is warming up], setting the scene for a great night.
Then, the song zooms in on one specific person who is absolutely owning the dance floor. The singer describes a woman who "Baila como diosa" [Dances like a goddess] and makes the pretty wild claim that "Beyoncé y Rhianna la van a envidiar" [Beyoncé and Rihanna are going to envy her]. The imagery gets even more intense with the line, "Sudaba tequila yo quiero probar" [She was sweating tequila, I want to taste it]. It's a high-energy celebration of dancing with complete confidence.
