The death of a certain very large music tracker a few years ago kicked me into full hoarding mode. I realize I may never read/play/listen to some of what I download, and that's fine.
Typically, I won't download something if I am not going to immediately start experiencing it.
This too is fine.
What is important is that you don't spend alot of time/worry fussing about and just enjoy your collection. Admittedly I have some worry about it getting lost, but ultimately one has to realize that such concerns are fleeting.
