All of the ones I own - thank goodness for writable CDs. Some in their original state, if not enjoyed completely, I’ll delete tracks. If I need to delete too many I’ll purchase more from the same artist and put together a "best liked" compilation. I have a bunch like these, all pop/rock genre. So whenever I pull a CD to listen to, I can be assured of no clinkers looming. Still, most of my collection are entirely enjoyable from first to last track as originally released. Far too many to list.
