It’s not about having to listen to every record, it’s about having a source of reference and being able to access something as the mood takes or to share with friends- I have about 1000 lps (mostly from auction sales and stuff from family and bought new in earlier times) and between 600- 1000 CDs all bought by me new but have definitlely reached saturation point
Also have over 60 pushbikes which are all loved and ridden (mostly bought for pennies from the auction and renovated) but again am going to find good homes for half of them over the coming years
My dad was a stamp collector as it was like a history/ geography lesson then bought more expensive ones as an investment- I sold his collection with a specialist auction and got £10,000 which was a massive help with building repairs.
Some collectors end up becoming dealers, also I remember the enjoyment of visiting Mole Jazz, Ray's, Honest Jon's etc in search of specific titles but now it's all (mostly) just there if you want it streamed or e-bay etc
