BreatheHeavy has a new theme song, and it's sung by Sia.
Funny story... the single was originally meant for Adele (which finally sees a proper release date).
“It’s about [her] life, so now I sing the song from [her] perspective,” Sia told RTVSlo recently. “I have these songs made and they have [been] rejected, but [they] seemed… good, so I kept [them for] myself.”
The "Chandelier" singer debuted the cover art earlier this week, an androgynous photo where Sia, in typical fashion, makes no appearance.
