Carrie Underwood wants to make country music appealing around the world.

The 29-year-old singer - who has sold over 14 million albums since winning American Idol in 2005 - thinks it is sad the genre isn't as popular in other countries as it is in the US.

"It's always fun to expand your resume. Country music isn't too popular outside the US and that's something I'd like to change. It's a shame other people aren't exposed on a daily basis to such a wonderful form of music," she said.

Carrie admits she was told she would find appearing on American Idol difficult because of her country roots, but she always had the backing of then-head judge Simon Cowell and didn't have to change or conform.

"From the beginning I was told, 'It's going to be rough for you, it's a pop TV show.' But everything I did just came out country. And Simon encouraged me to stick at what I do well. My goal is to make country music everyone can get into," she added.
