re: playlists.I've always said its a double edged sword.Posting a playlist can give,or take away,credibilty.If its a good playlist,it should attract people to the venue.
Some promoters like the idea.Some don't want one posting,for the reasons stated by Terry.Always ask the promoter, if you want to post a playlist up.
Adding WDJ or whatever doesn't bother me at all.Better than no labels,leaving a question mark over originality? After all,that's what most arguments on here are about,ie: this thread.
