When filesharing and CDJs arrived I lost all interest in music for a while. It all became filecollecting/"sharing".I think it changes things certainly. Men my age get all watery eyed at having had very small record collections and needing to make a decision about which album to buy next - often a thought process that would last for weeks.
The silly amounts spent on 12s was a rite of passage for some, certainly was for me. Some would also call it sunk costs.
