This article is absolute nonsense and a disgrace to the field of addictology. I hope no one reads this trash and thinks it's factual. You almost had me.
I once walked past a copy of the DSM IV-TR in 2003 and can confidently state that an addiction to rocking is defined as "the fact or condition of being addicted to Van Halen, The Scorpions, and Prince or similar acts while wearing a leather jacket".
