I know when you convert an audio cd into mp3s, you can use the CDDB database. Is there anyway to make mp3s into an audio cd, so in the future, if I wanted to convert the audio cd into mp3s, it will use the CDDB database? I know each cd has a code which tells the database it is a certain artist and album. Also what is the difference between ID3v1 and ID3v2? Do they have anything to do with this coding or with the CDDB database? If so is there a certain program that I need to achieve this? Any website regarding this would be helpful too. I have over 500 full albums in mp3 format that I want to burn to audio cd and get them off my hard drive. I have no need to burn them as mp3s to CDRs. I have cd players in my home and cars; no mp3 players. Also I hardly listen to music on my computer, unless checking the sound quality of mp3s.
