Following Leona Lewis’ sophomore flop -- Echo -- in the US (190,000+ units sold to date), one of the album’s main collaborators, Ryan Tedder, gives his opinion on why he thinks it failed:
“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 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"
