I might agree with the above, although a friend of mine inisists that some are more prone to losing data than others (immediately, and after time). We burned some demo CDs on some BASF CDRs that we bought from Guitar Center, and they were pretty nice. THey had a ceramic coating on the top. THey might not sound any different, but they're heavier...they may be more stable in the player (that's my quasi-scientific take on it, anyway).
