Tøp they are awesome, and I know what you mean about not being able to pick a favorite song. It drives most people crazy when they ask and I can't answer.
As for the cats, you can never have to many. I have ten, I take in pretty much every cat I see on the street (that doesn't have an owner of course), one of them is actually pregnant now, so I'll probably be really close to the number 15 soon.
