Songs that randomly and frequently get stuck in my head

Usually just the chorus
  1. The "It's Possible" song from Rodgers & Hammersteins "Cinderella"
    Brandy and Whitney Houston, need I say more.
  2. Marc Cohn, "Walking in Memphis"
    Put on my blue suede shoes and I boarded the plane ...
  3. Nelly, "Hot in Herre"
    Every time I'm the slightest bit too warm
  4. Zac Efron (High School Musical 2), "Bet On It"
  5. Chicago, "You're the Inspiration"
    Always triggered by the word inspiration
  6. Tracy Chapman, "Fast Car"
    I barely know any lyrics, it's like mumbling to the tune in my head until the chorus.
