• Bassist Jay DeMarcus co-wrote this song along with Hillary Lindsey and James Slater. He told CMT News about the writing of this song: "Hillary Lindsey and I had had a melody that we had been working on for almost two years. James Slater came over and joined us one afternoon and had this title, 'Unstoppable.' As soon as we heard that title, it spilled out of us. It was like a no-brainer right there. The power of love - you can sit and write all day about it. I think we had to edit a lot of our thoughts because when you think about the ability of love being unstoppable, and all that love can do when everything else fails, even when you're at your lowest point - I think that was the message that we want to get across. At the end of the day when all is said and done and everything goes to hell in a handbasket, you know that love will be there to pick you back up. That was kind of a cool thought. We had never approached it from that angle before. We sing about love a lot but never had approached it from that particular angle."
• Unstoppable was Rascal Flatts' fourth #1 on the Billboard Hot 100 in the 21st century. This achievement meant that the trio became the first group to attain over three chart-topping long players since the millennium.
• An adapted version of this song was used as the theme for athletes at the Vancouver 2010 Winter Olympics. Guitarist Joe Don Rooney explained to AOL's The Boot: "AT&T and NBC came to us about the song, and they wanted to change it into more of an anthemic thing before the Olympics -- not just about love but about you being unstoppable ... like an Olympic athlete, for instance. So Jay [DeMarcus] got with the writers, Hillary Lindsey and James Slater, and rewrote the song to fit more of that theme, and it turned out killer."
