With CDs losing data in the 5-20 year lifespan, that makes them terrible as an “archival data” system.
I guess that depends on how often you play them. When I was young I played certain records and cassettes so much they wore out and/or lost sound qualilty pretty fast. For that type scenario, CD's are a pretty good medium. If you are just going to store them in a drawer, then not so much.

I still have a lot of CD’s from the 1980’s. All playing fine.
