Foolestroupe:
I know what you mean, but CD audio is not to be confused with "lossy formats" like MP3.

If you archive stuff on CDR in CD-ROM format, i.e. as files instead of CD-Audio format, you will get stronger error correction and a bit perfect copy, if you get a copy at all.

Modern CDR media are far less prone to degradation that they used to be, if kept out of excessive heat and light. If you're worried about losing the data, probably a good idea to copy it occasionally to keep it fresh. And any other storage media has the same problem, to some extent.
