It's not an uncommon problem. I stopped using them years ago. For tiny runs - less than 50 - I use a printable CD and write on it in black ink (not ballpoint). For larger runs, I have them professionally printed.

The main problem with the sticky labels is that they can add a significant extra thickness to the CD - which can be critical in a non-tray, slotted player. This thickness can lead to rubbing in the slot - and then the sticky label catches... and you know the rest.
