I'm trying to make an audio CD for my girlfriend, that is, a CD of his songs 
(she's a song writer/interpreter/maker) and I'm trying to make it as perfect 
as possible. I'd like to fill all the fields and have cddb entries for it.
So, does anybody know what are this fields (that k3b shows me).
For tracks: ISRC. What does Preemphasis mean and what will happen if it is 
Copy Protected ?
For the whole disk, what are the fields UPC EAN and Disk Id ?
How are cddb entries generated ? do they depend on some of those IDs ?
If I wanted to add mp3/oggs to that CD, how should I do it so old players 
would play it ?
Thanks
