What do you mean one track at a time? I dont understand...
CDDB is the cd database. You click on that and KSCD will contact the online database to put the band name and track nae of the each track into kscd, so instead of havinf track1, track2, etc, you will have the real name of the song at that track, for example, Blind-guardian---battalions-of-fear, or whatever..
Also there is Grip, workman and a lot of other ones if you don't like kscd.
