Okay, so Dirty Harry is actually a song that was made by a band called Gorillaz. They made the song to talk about how the world can be a little bit crazy sometimes, especially when it comes to violence and crime.
The lyrics talk about a character named Dirty Harry who is a cop who wants to stop all the bad guys and make the world a better place. He's like a superhero in a way!
The song has a really cool beat that makes you want to dance, and it also has some cool sounds from instruments like the piano and the trumpet.
Overall, it's a really fun song to listen to, but it also has a important message about making the world a better place and fighting against crime.
