It's like the radio. Yes, there are some classics you always go back to but there's also a constant stream of new music entering the mix as other music exits it. Not to mention the underavailability of music on a service like Bandcamp. What % of the top Spotify tracks can actually be bought there?
Don't get me wrong, I'm no fan of Spotify. But streaming music ushered in a new way for people to interact with music. I personally think it's worse but clearly plenty of people disagree. And I think we wear rose tinted glasses when looking at the past. I’m old enough that I actually did buy albums back in the day, I have a great memory of running out to get Radiohead’s Kid A then sitting in my room listening to it in its entirety. But if I were to actually take stock of how many of those albums I still listen to today… I can’t even remember a load of them. There were a bunch of misses on there that I’d probably have been better off not buying.
