Given what you're going to get for them, maybe $1-2 each based on what eBay lots go for, I'd keep them. I don't sell CDs I don't like, and every once in a while pull something out from my B-list and actually end up enjoying it...then again, this bears no relevance to your situation, but there are legal issues, and well, a CD is about as "solid state" as you can get. You can shake it, drop it, throw it, wash it, and the data will still be there.
You won't get a fortune out of selling them. I like my large collection. It looks cool. :)
