That's really strange. I've never actually contacted them about this problem myself, but I've heard it was an issue and have heard people had success with contacting them. Here is the help page. I think the "contact us" part is what you'd use. Good luck.

Are there any rules to what songs should be added on the playlist other than the 2 songs per artist limit? Was thinking about adding some stuff. Wasn't sure if we were supposed to try and add similar stuff to what you have there, or just anything at all.
