I was listening to this in my car and noticed a ticking noise on the first disc about half way through. As it played, the ticking became louder and louder and by the end of the disc it was unlistenable. Took it back to Best Buy, and as i waited for the "oh so pleasant" customer service guy to proove me wrong, he says he doesn't hear it. Big surprise. So I nicely ask for a new one, and they oblige. Well, it does the same thing starting at the same spot. Anyone hear this or am I going insane?
