Seriously addicted to rock music (rockers) are often compared to drug addicts. And this is no coincidence. They can no longer give up rock music, and in ever-increasing doses. One Japanese rocoman admitted guilelessly: "Rock is like a drug, just not prosecuted and much cheaper." There is a need to constantly listen to more and more new recordings. For the manufacturer of such a potion, this is an ideal buyer, the market is provided for him, and, most importantly, in ever-increasing sizes. Rocker, like a drug addict, goes to great lengths to get his "portion" of rock.
