The song wasn't written expressly for the games (it first appeared on Matisyahu's 2009 album Light), but the themes and goals of the track ended up applying perfectly. "I wanted to write a song that was an accessible global anthem for hope and peace," the MC told MTV News. "I don't know exactly how it came about, but somebody heard it and thought it would be a good fit."
Since the start of the games, "One Day" has popped up in a number of places during NBC's broadcasts, from soundtracking montages to scoring bumpers. The MC even got the opportunity to travel to Vancouver for a few days. While he was there, he felt the positive vibe that has extended to everybody in Vancouver around the games. "I had one moment when we were performing and we were playing 'One Day' and I looked out into the crowd and saw all these different flags," he explained. "Everybody has their flags, and it was a really cool feeling feeling — a utopian kind of feeling."
Even though he doesn't consider himself much of a Winter Olympics enthusiast, he has plenty of background in some of the biggest sports of the games. "I played hockey growing up and it's a sport I really enjoy. I also worked on a ski mountain for a few years and got into snowboarding, so I'm something of a winter sports kind of guy," he said. As a result, he has been deeply invested in the United States' ongoing improbable run (including their upset victory over Canada). If nothing else, it keeps things interesting while he's on the road (continuing a tour that will last well into the spring). "Some guys in my band are Canadian, and we all grew up playing hockey, so there's a friendly rivalry happening."
