I still haven't heard back from ABC, but I HAVE been seeing the same info Alice mentions above.It seems as if the list was originally sent out as "songs to be aware might be considered sensitive", which was taken as a list of banned songs by (apparently) several stations. Shortly thereafter (from the interviews with DJ's, within minutes) came a clarifying email stating that the list was not a "ban" list, but a list of songs that might be considered sensitive to the community, and that Station Managers should take it under advisement.
As to where that list originated, nothing but speculation is currently available.
