Can too much of one CD hurt you?

For the past couple days, I've been listening pretty much continually to one particular Belle & Sebastian CD. Can this be good for my brain? I'm not sure. Luckily Josh played a wide variety of music off his computer yesterday, so I did take a little breather from Dear Catastrophe Waitress. (nope, can't even branch out to other Belle & Sebastian CDs, it's all Dear Catastrophe Waitress.) I have no idea what spurned this new interest. It's not like it's a brand new CD or anything. I've had it for a while and I've always liked it.
