Editor's Note: First Notes is a weekly update of recent happenings in the world of music.
* There's a new version of "Do They Know It's Christmas?" by Band Aid 30 featuring Bono, Chris Martin, Ellie Goulding, Sam Smith, Rita Ora, Elbow, Ed Sheeran, Bastille and more. Money raised goes to fight Ebola. The original charity single was recorded in 1984.
* Chinese singer Rong "Rollin" Wang released a bizarre video for her song "Chick Chick," that looks to be capitalizing on the success of Ylvis' "What Does the Fox Say?" and Psy's "Gangnam Style."
* Sinead O'Connor, in a lengthy interview with the UK's Daily Mail, wasn't a fan of U2 forcing their album on people, referring to it as being something "almost terrorist."
