R+B star John Legend believes his hit song Ordinary People can help solve relationship problems.

Legend, who penned the ballad with THE Black Eyed Peas rapper WILL.I.AM., claims the song allows listeners to visualise their issues, and helps them to gain a different perspective.

He says, "People always tell me (that song) helped save their relationship or helped them think about their relationship or helped them talk through things.

"There's almost a therapeutic component of the album as well where it helps people visualise what they are going through and think of it in a different way."
