"Happy" failed to break into the American Top 20, a fact that did not greatly surprise Tedder. He explained to Digital Spy
"I know exactly why and I actually told the label what was going to happen. In the US, unless you're Justin Timberlake or Beyoncé, you cannot
put out a song and not be in the country when it comes out. Leona was gone for six weeks when 'Happy' came out because she was promoting the record in other countries - it wasn't her fault; she just couldn't be two places in once. I had radio stations telling me that they thought 'Happy' was the single biggest ballad they'd come across in ten years, but that if Leona didn't come over here and promote it, it was going to fall. On top of that, America's consumed with Lady Gaga and dance music right now, so it's not the best time for ballads anyway. When everything on the radio is blasting out at 120 bpm, a song like 'Happy' almost sounds out-of-place."
Tedder added that he asked the record company to release "Happy" later. He said: "I asked them to do what they did with 'Bleeding Love'. They should have waited until it became a proper hit in loads of different countries and then put it out in the States. For whatever reason, it had already been decided that the release was going to be simultaneous. From the day 'Happy' came out I never felt completely confident. It was very disheartening because I've never put so much time into one song."
