Rebuilding database with new bookid

[Roy Dennis]

There's no automatic way to do that to the best of my knowledge.

Are you referring to Importing tracks from CD or individual downloads ?

Depending which version you are running you can tag new songs onto an existing Disc Id in the import Hard drive files dialog up to a total of 99 tracks per Disc ID.
But you can't do that with CD importing.

I ask which version you are using because older versions would overwrite the existing tracks unless you rename the files with a track # higher than the last track already allocated to the disc Id.
