I did it (collect LPs/ music) because it became an addiction, almost like a disease.
Yup, as you say, exactly. Very much like a disease!
And this can reach ridiculous levels on classical: +500 LPs and a few cds of Beethoven Symphonies & p. concerti + violin concerto; +200 on Mahler's symphonies...
I used to have ~4000 LPs & ~2000 cds for "current listening" and another 6000 LPs (forgotten) in boxes...
I'm pretty reasonable nowadays having, as Albert above, selected amongst the cds & LPs the ones I really want... in all, ~5000 LP and ~ 1.500 cds (~75% classical).
At the end of the day, I can't anymore afford the sport of buying, listening and reselling (or keeping) s/ware anymore (two kids, one wife, etc).
