Musicón is a colloquial and emphatic term derived from "música" (music) with the augmentative suffix "-ón". It doesn't just mean "big music" literally, but rather implies loud, powerful, and often party-ready music.
In the context of the song, the artist repeatedly says "Préndeme el musicón" (Turn on the big music/party music), indicating a desire to crank up the volume and get the party started to forget about a past relationship. It's an engaging and less common way to refer to music, making it memorable.
Get ready to move with Don Miguelo and Chimbala's "Coge Tu Camino"! This song is all about moving on from a bad relationship with a bang. Our singer is completely over his ex, who apparently did him wrong even though he was a "vacano" [cool guy] and never cheated. He's telling her, "Así que coge tu camino, que yo cojo el mió" [So take your path, I'll take mine].
He's not just moving on; he's celebrating his freedom! He wants to "préndeme el musicón" [turn on the loud music] and "quiero bebe', que quiero gata'" [I want to drink, I want girls]. It sounds like his ex is having a harder time, getting drunk and calling him restricted, but he's not having it. He's found someone new who "me controla" [controls me] and he's ready to party with his friends. It's a fun, energetic anthem for anyone who's ready to say goodbye to drama and hello to a good time!
