I would have to augment my other collecting interests; Newspapers, Coins, and my favorite pastime, collecting vinyl. Similar to collecting cards... a person has to search through boxes of A-ha, and Flock of Seagulls albums to find that rare slab of sound. Collecting records tends to have some focus, usually by genre.

My Vintage Vinyl interest: No, not 16 or 78 RPM slabs... but obscure 60's psychedelia (13th Floor Elevators, The Count Five, etc.), and 70's punk rock (Radio Birdman, The Wipers, Dead Boys, etc). I feel bad for those left with the stacks and stacks of wax after I'm gone but just "put the headphones on and drop the moon-rock needle".
