Latin heart-throb Enrique Iglesias insists he's proud his hit Hero is a karaoke favourite - because the song has had a huge impact on so many peoples' lives. The singer, who released Hero in 2002, is adamant he doesn't mind his tunes being performed by amateur singers, as he doesn't take himself seriously. He says, "It feels good to hear other people sing it. "It was a song I wrote in my bedroom. It's cool. It tells you the power of song. It's good it's had such an impact. I don't take myself so seriously that I get upset when I see someone sing a bad version of it."
