Help with a de-emphasis list?

WOW! I just popped an old CD, that has always sounded crappy, into one of my players that happens to have a de-emphasis circuit and this thing sounds like an LP! I don't see any way to identify this in/on the packaging. Anybody have an idea how much music was coded this way? A list of favorites? The CD of mine is Tom Petty "Southern Accents". Is this niche worth rediscovering?
