News flash: popular music is full of references to drugs and alcohol. Okay, not a big surprise, but the sheer volume of drink and drug mentions is now quantified in a study by the University of Pittsburgh School of Medicine, which finds positive mentions in two thirds of recent hit songs and mentions of substance abuse in one third of those hits. Also no big surprise: drug and alcohol references are most prevalent in rap and country. I will also not be surprised if there follows a lot of hand-wringing about how rap’s favorable attitude toward drugs and alcohol is endangering our kids — and a lot of shoulder-shrugging about the same content in country. Snoop’s a menace, and so is Three 6 Mafia, but Toby Keith (pictured) may still sing “Beer for My Horses,” and Joe Nichols may still sing “Tequila Makes Her Clothes Fall Off,” without anyone batting an eye. Party on, everyone!
