Sex, drugs, and rock and roll!

And they needed a *study* for this? How much did this cost; I could have told them for free.

I agree with jatfla! They could just ask anyone. Drinking songs and other such miscreant mischief in songs have been around for centuries....

Phew, what a relief

Any music is typically awash in the humanity of the songwriter and often reflected by the singer. Popular music can also reflect love, relationships, kindness, generosity, healing, heartbreak, sadness....

I'm not sure if

"Tequila makes her clothes fall off" and "Breakin down the good weed, rollin' the blunt/Ghetto pimp tight girls say I'm the man."

should be classified as 'popular' music. I've never heard any of those songs before. jatfla makes a good point; why spend money on a survey like this when you could ask the listeners for free.

The music for The Star-Spangled Banner is from an old English drinking song, To Anacreon In Heaven.
