If someone looked through you music (records, CDs, etc.) what would surprise them?

Wait, I thought cat hair on a special pressing LPs just gave them  more.....ah, you know, texture? 
The last cat I had would sit for very long periods of time trying to "catch" the cursor on my computer monitor...sometimes on the front of the screen and sometimes on the back...  more than once I lost a mouthful of coffee onto the screen from laughing. 

That after 2 hours they are thinking they should have brought a lunch.

The number of cd's makes their heads spin so they can't choose.

Not one rock piece.

In the approx. 1300 classic rock, jazz, blues, etc. lps they'll find a nine pack of Michael Jackson seven inch 45's.  Can't remember where they came from.
