Maybe this can be done directly when you rip a CD (and if so how??!) but instead of having Album CD1, Album CD2 etc I like to have \Album\01 - track name right up to \Album\45 - track name.mp3 etc. But when I rip each CD gets ripped from track 1 to X and I can't change that there. What's the easiest way with MP3Tag to increase all track numbers in an album by 15 (for example), so instead of 1, 2, 3...12 they read 16, 17, 18... 27

You can either use the auto numbering wizard that has several options for renumbering, or you can use a Format values action with something like $add(%track%,15) applied to the TRACK field.
