"Excuse Me Mr Sir" by Avicii (ft. Vargas & Lagola) is a song that speaks from the perspective of a successful artist who has traveled a long path and is proud of his accomplishments. The song talks about how he has always put in the work and gone against the odds to make a name for himself.

The chorus lines suggest he is the reason for the audience's enjoyment as they keep coming back to see him perform. He's like a rollercoaster, a wildcard and a riot which is exactly what people need.

The bridge is a response to someone from the outside trying to understand the world he comes from and his way of life. "Excuse me, Mr Sir, I don't understand your world" could be taken as a response to outsiders who do not understand what it is like to be an artist of his caliber.

Overall, "Excuse Me Mr Sir" is a song of pride and power, with an underlying tone that speaks to the struggles of making it in the music industry and needing to always put on a show to keep people interested.
