So, here's a weird one.

I have an album that's been ripped from vinyl &, for whatever reason, the person responsible has started the numbering from 0.

So, I have track numbers 0-59 instead of 1-60.

Is there a way of increasing the track numbers by 1?

Obviously, I can type 60 into the track total. Would I need to do that first, to "make room" for the extra track? (I assume the total number of tracks can't be lower than the actual number of tracks.)

Sorry, I read your post incorrectly. That's my old eyes reading on a phone.

You can select the tracks and simply do an Actions>Renumber Tracks>From... and enter 1. That will ignore any possible disc or album differences.

You can manually change the Total Tracks to 60 or select the files and do an Actions>Calculate Track Count>Absolute
