When you say “leaked”, do you mean the tracklist and art, or the recordings themselves? If the second, then the proper way to handle it would be to create a new release in the group reflecting the official album and leaving the existing entity because it’s a perfectly viable bootleg/demo release. Even if it’s the first, there still might be an argument to be made for leaving this one, I’m not entirely sure. I’m not voting “no” quite yet just in case it is the first and the others here don’t think it’s necessary to keep, but I’m definitely leaning that way.
Also, did you mean to create a new recording for L.A.LOVE? If not and this edit goes through, we’re probably going to want to merge the two afterward.
