The singer-songwriter's next single, "Alive," was originally written for and with Adele and co-writer Tobias Jesso Jr., but according to RTV Slovenija (translated via Google Translator), Sia said Adele rejected the track at the last minute. Nevertheless, she decided to take on the track anyway. “It’s about [Adele’s] life, so I now sing a song from [Adele’s] perspective,” she told the outlet.
"Alive," which will be released Sept. 26, is the lead single from Sia's upcoming album This Is Acting. The song coincidentally works perfectly with the theme of the LP, as Sia told NME in February that the title stems from creating songs not necessarily meant for herself. “I’m calling it This Is Acting because they are songs I was writing for other people, so I didn’t go into it thinking, ‘This is something I would say,'” she said. “It’s more like play-acting. It’s fun.”
