I've been thinking about this whole availability thing, from a number of perspectives, especially as music is so easy to listen to now. For example: I am typing this while listening to a playlist of tracks I've never heard before on spotify... Absolutely unthinkable when I was 18 in 1991.
And sure... I probably know "Too Dark Park" by Skinny Puppy or "Master of Puppets" by Metallica more intimately than I'll ever know anything else again because I could only buy one album a month and would play them on repeat for ever, but would I go back to that? f*** no!
In the same way that a starving man wouldn't want to go back to the time he found a piece of mars bar in a hedge, and when he ate it, it was the best mars bar he'd ever because he hadn't eaten in a week. No. Those days are gone.
Incidentally all my first stuff was broken sh*t from 2nd hand shops. My first bass was a short scale piece of crap with no name on it that barely made a noise over the hiss, and one of my first guitars, the electronics fell out, along with what looked like hay.
In short, I'm not completely against the old definition of nostalgia as an illness. http://knowledgenuts.com/2014/06/29/when-nostalgia-was-considered-a-crippling-mental-illness/
No, things weren't better back in the day. The truth is you were young, full of wonder, everything was new and your memories are partially false and partially rose-tinted.
