A song can have any number of meanings to whoever hears it. No matter how straightforward the song is, people will interpret it differently.

Billboard.com has a list of '10 Songs That Aren't About What You Think They Are.' Here are some highlights:

"Summer of '69" by Bryan Adams. He would've only been nine in 1969 and back in 2008, he confirmed that despite the apostrophe before '69 in the title, it was a "sexual reference" and not about the year.

"Closing Time" by Semisonic. It isn't about drunk people being tossed from bars. Singer Dan Wilson has said many times that it's actually about the child that he and his girlfriend were expecting, "I had birth on the brain. I was struck by what a funny pun it was to be bounced from the womb."

"(You Gotta) Fight for Your Right (to Party)" by The Beastie Boys. It's supposed to be a joke, spoofing '80s bands like Motley Crue and Twisted Sister. Not the straight-up party anthem it became.

"Got to Get You Into My Life" by The Beatles. Paul McCartney says it's, "an ode to pot, like someone else might write an ode to chocolate."

"Total Eclipse of the Heart" by Bonnie Tyler. It's actually about vampires falling in love. It was written by Meat Loaf's songwriter Jim Steinman, for a musical version of "Nosferatu".
