I doubted Bleeding Love's US success, just because I thought the US wouldn't like a song like that
I also doubted;
Gabriella Cilmi - Sweet About Me (Love the song, but I didn't think it would be a hit

)
Ne-Yo - Closer (Love it, but it's not like his other stuff)
Dance Wiv Me - Dizzee Rascal (Love it as well, but none of his singles have had major success)
