Thanks for your review and comments. I know I don't need the votes, it was more of a request for feedback on what I had done so far.
I thought about adding a label for that release, but I truly do not know who is doing the bootleg release. Presumably they target releases from many different labels, so without more information about them (Discogs does not have more info), I decided I would not just make up a name. Maybe I should use [no label]?
I've seen the konami-command scripts, but thought I would understand the process better by doing merges by hand before automating the task.
Again, thanks for the review.
