The most important consideration... unlike the difference between cassette and vinyl (the options before CDs), there is absolutely no audible difference whatsoever between CDs and CD-Rs - assuming identical programme material, of course.

Unless you happen to belong to that group of nutters who used to believe you could make a CD sound better by drawing around its edge with a special green felt pen...!

The enemy of a CD-R is ultraviolet light - store them in the dark.
