Why so much????

In response to a post appearing here yesterday a number of 'AGon-people' claimed to have CD and vinyl collections numbering in the hundreds and even thousands. Other posters questioned the need for so much music (impossible to listen to all of it!) while others spoke of a pissing contest among the 'overly endowed'.
Your thoughts are requested for the following questions:
1) How much is too much?
2) To those with so much...Why? What's your rationale?
3) Are you crazy?

Just curious. I'll give my thoughts later.
