Entrance music is the music that plays when someone walks into a room or onto a stage. It's usually a special song that the person chooses because it makes them feel powerful or important. Do you know how sometimes when you hear your favorite song, you want to dance or sing along? It's the same for people who have entrance music. They want to feel cool or powerful when they walk into a room, so they pick a song that makes them feel that way. Sometimes wrestlers or athletes also have entrance music when they come out to compete, to pump them up before their match.
