how to make the music better

so I put music individually in each and every one of my scenes but when i go to the next scene the music plays again from the beginning

my levels are really short so the music plays for about five seconds

I want the music to play all the time in all the scenes without starting over again

btw the music is in video form i recorded the music and then imported and into unity and set it so only the audio appears

Generally speaking you have to use DontDestroyOnLoad. With this implementation your script will persist between scenes, so the class does not get destroyed when loading a new scene.
