Defective CD's

I ordered this some time ago and have been listening to the CD's chronologically over the last several months...until I got midway through and have found these album CD's to be defective and will not play through the entire album correctly. I have tried on another player with the same results. It is very disappointing obviously and I do not know what to do as it has been almost a year now since I originally purchased? These were suppose to be "new."
