I realized that I needed to add more metadata to the mp3s that I have on my page. I've done this with an mp3 editor and I'm ready to upload and replace the files that I have on my page (I have a Soundcloud pro account btw). I have a private playlist that I've been sending out to music blogs and my question is: when I upload and replace the existing tracks will the new tracks automatically go into the playlist that I've been using? I'm worried that when I upload and replace with the new versions that this won't happen and I'll need to create a new playlist and that the link that I've sent out already will no longer be usable. Does anyone have any experience with this?
