Anybody willing to admit?

No - in fact, I'd have to admit to just the opposite, the inability to get rid of titles I don't like. I'm "only" approaching about 1000 CDs, so maybe it'll change as it becomes more obvious that there has to be titles I don't like / never listen to, but so far it's pretty much if I buy it, I keep it. The only exception is when I hear somebody say they love something I don't care for and that they're going to buy it - then I just give it to them for the brownie points. I'm the same way with books. -Kirk

I only have 12 Opera cd's, and don't like or listen to any of them. I shelve them (7 are box sets) on top of my CD bookcase, not even on the shelves, which must be used for more valuable disks, and they are gathering dust. I should sell them I guess, but what is a record/cd collection without at least an entry for opera?

Hmmm some day I will have to sell part of my digital and analogue collection, but I'm lazy to place my ads on the net.
I've never used to keep more than 150 records and sold whatever I've listened and bought something new. Whatever records I can get again later I would sell to pack up my shelves with something new that I'd like to listen or listened a long time ago.
Now I own 700 vinyls where at least 30% I don't listen anymore and want to sell.

Two things I accumulate is LP's/CD's and wires (I have a box of wires and don't have a clue what to do with them all). I listen to half of the music I own as it is, yet still keep buying more new titles. People with 5000 LP's certainly have their hands full, I have no idea how they would have time to ever listen to even a portion of them.

I don't know the numbers but I have what seems to me like a lot of CDs and records (and DATs, and even some cassettes!). Just about everytime I've gotten rid of something I've regretted it, although I do come up with schemes to "simplify" fairly often. So, I'm holding on to all my music. To those that can travel lighter in this world, my hat is off to you!
