Today's Daily Download is a beautiful song from Australian singer Sia, called "Elastic Heart". It features on her latest album 1000 Forms of Fear and it's also on the soundtrack to the latest Hunger Games movie, Hunger Games: Catching Fire. I'm sure a lot of you have heard about the video before the song itself, it stars US actor Shia LaBeouf and it caused uproar - because it showed him wearing a nude coloured leotard, while dancing in a cage with 12 year-old Maddie Ziegler, who also features in Sia's "Chandelier" video. Sia later apologised to those who were offended, saying "my intention was to create some emotional content, not to upset anybody". Here it is, this is Sia with "Elastic Heart" and it's Thursday's Daily Download.
