The CD player in my car went haywire. CD's were skipping and others wouldn't play at all. Thought maybe it may need a "clean up."  WOW! Put this in the CD player...ran it twice. That's all it took. And to think, I was ready to pay to have a new one installed. Have to agree with others...don't buy a new CD player before trying this. Besides, the music on the CD isn't so bad either...yes...there's music on the CD cleaner.
