Hi everyone,
I have the following question.
I've ripped a huge multi-artist collection with over 100 CDs and want to automatically do the following:
1. In the artist tag field I have the following name: Marv[space]Johnson
2. I want to automatically, somehow, change this into: Johnson[comma][space]Marv
3. I have to do this for most of 1700 files, so some automatic process would be helpful.
Note: Most (but not all) artists are like this, so this should work (only) for all the selected files (and leave the ones that are different - not selected - untouched).
Is this at all possible?
Thanks for your help or any hints as to how I could go about doing this.
Since mp3tag can do just about everything but bring one's slippers to the bedroom in the mornings, I suspect there is a way?
