Singer Rihanna used to get three-year-old children to help her choose which singles to release because they love "great melodies".

The singer found playing her music to children was a good indicator as to what would do well, reports femalefirst.co.uk.

She said: "I'd play my songs to my A&R's kids and see which ones they'd react to. They were three-years-old. Kids just love great melodies."

The 27-year-old compared her songs to tattoos.

She said: "I can't make a song for a particular person or demographic. If I love it, I'm gonna do it. I have to perform it for the rest of my life. A song is like a tattoo - you can never get away from it.

"You can't stand behind something you don't believe in. You can pretend for a little while, but there's always going to be resentment. I can be who I am and sleep at night, knowing there's no pressure to be anything else."
