If you decide to use CD-Rs, you might consider printable discs and print a label directly to the disc rather than use the stick on labels. Some people claim to have good luck with the stick on labels but they will not play in my truck. Instead they jam into the slot and are difficult to remove. They could be a problem in any player with a narrow slot instead of a drawer. Printers that print directly on CDs are not that expensive.   I have an HP printer that prints to CDs and does the usual printing jobs as well and purchased it for around $100.
