I have 100+/- albums collected over thirty years. As others, its a crapless collection. Though I am not to be relied upon for good judgement in terms of crap/gems. There is also no room for anything that is just "good". Nor anything that belongs in a collection "just because". You know, as advertised: "every metal collection must include this album." That sort of thing.
At one point I did have about twice as many albums. I lost them in an accident. Which is a polite way of saying I burned the house down and everything in it.
When it came time to replace them, I thought about which ones I was really missing. Wasnt missing it? Didnt need it.
