For every hour that American teens listen to music, they hear more than three references to brand-name alcohol -- about 34 in the course of day.

This heavy exposure could contribute to youth addiction, according to a University of Pittsburgh and Dartmouth University study published online in the international journal, Addiction.

Researchers point the finger clearly at rap, R&B and hip-hop artists, who they say promote a "luxury lifestyle characterized by degrading sexual activity, wealth, partying, violence and the use of drugs."

Although the alcohol trade industries publicly say they do not market to underage drinkers, researchers said the line is "difficult to distinguish" because liquor companies "retroactively reward" the recording artists with product sponsorships and endorsements when songs climb the charts.

This music is so popular among high school students that the study concludes the relationship between the two industries could encourage young people to begin alcohol use early and to continue drink throughout their teenage years.
