I am not a professional grader, I try to get the grades as close as I can without over selling. For the case please look at the pictures as that is the best indicator of condition. For the CD I play them on my Yamaha CDC-575. I listen to all the CDs I sell the whole way though because there may be light scratches here or there and I want to make sure they sound good. I'm not perfect I do get distracted once in awhile while listening to them so if there is an issue just message me and I'll make it right.
