Shania Twain's first single for six years was this self-empowerment anthem, which she co-produced with Nashville producer Nathan Chapman (Taylor Swift). The Canadian songstress debuted the song on the June 12, 2011 series finale of her reality television show, Why Not? With Shania Twain, and the tune was sent directly to radio stations nationwide, and made available to fans via iTunes. "I wrote this song in real time as the series developed," she told Perez Hilton. "I'm so excited! I can't believe it!"
Twain explained the inspiration for this song: "The purpose of writing 'Today Is Your Day' in the first place was self-inspiration," she said. "I was talking to myself and saying, 'Today is your day. You can do it!' But the decision to even write the song and share it was a big decision for me, to find myself as a songwriter again, independently, for the very first time after all these years."
