I can help you understand the lyrics to "Master of Macarena," but there doesn't seem to be a song by Petr Gorst with that title. However, the lyrics you provided are from Metallica's song "Master of Puppets." The song talks about the control and manipulation of someone's life, and the destructive power that the "master" has over their "puppet." The references to "Macarena" seem to be a playful addition, perhaps to lighten the mood or add some humor to the song. The song's intense and heavy sound reflects the themes of power and control. Overall, it's a song that delves into the complexities of human relationships and the impact of manipulation.
