Novice, well maybe you got some points cause an addiction to "fresh stuff" can occur, Im certain. But it would be really a huge simplification to think that buying those vinyls is a simple"shopping addiction", like you said. The real motor is usually the music, the message and the vibe and limitating this to a dunza thing is wrong. It is an addiction to reggae, and I think its great though the dunza thing can confuse it. Many people get this addiction with mp3's, they want new stuff, though they dont pay any penny for it, but still, they seek everyday for new stuff, new "injections"
The difference with heroin, is that you can get more and more and youll just feel better, until you do it truly and honnestly with yourself. "One good thing about music, when it hits, you feel no pain". So that seek for new sound is an expression of the connection of your soul with this music but you have to care for it!
Getting too much in the "collecting" way, spending to much, or consumming more than what you can appreciate at once can ruin your pleasure and you have to juggle with all that to find the healthy way to keep the connection alive and live it ina irie way.
