How do you get an annoying song out of your head?

I have a tendency to absent-mindedly hum or sing. My husband and I work together, and sometimes when I do this, I unfortunately pick a song that my husband finds very annoying and also has an impossible time getting out of his head. I just did this a moment ago with the internet meme song “Love Marriage,” and hubby’s mad. Any suggestions on how to get this earworm out of his head?
