YES YES! I have that too! *is totally shameless*
I have something of a cover!complex. There's a folder full of covers on my laptop. I'm really interested in how people rework things. I like to see how an artist relates to someone else's work and then "makes" it their own, adding/changing things and make something new using "old" stuff.
I think that's why I like all those furniture things made out of recycled stuff. All the reinventing that's behind them is really enthralling :) /babbling
