Okay, I've got to chime in. I'm not as bad as I used to be, mostly 'cause my two little boys keep me from roaming the racks like I used to. Also, years ago, I used to work in a store with used books, records, CDS, etc. Uggh. . .daily temptations! I've since pared down to just a couple thousand, and I still can't help myself whenever I'm at the local GW looking for abandoned audio treasures.
My guilty pleasures are novelty records, and the stupider the better! This includes sound effects, CB radio and trucker LPs, anything having to do with race cars or motorcycles, racy stuff from the 50s and 60s, any strange books being read on LP or famous people reading their stuff, motivational records from the 50s and 60s, stuff in other languages, etc. I've acquired quite a collection of really wacky, dumb, and strange records.
I did have a friend who once bought every copy she saw of Herb Alpert's Whipped Cream and Other Delights. She eventually wallpapered an entire room with the album covers. :yes:
Oh, and I almost forgot to add that I buy every K-Tel or Ronco compilation I see in good condition. Sick sick sick!
