Brit-rockers Coldplay have revealed that their hit 'Fix You' has previously been used to encourage horses to breed.

35-year-old Chris Martin admitted that he was once told a story of how a horse owner was struggling to get his animal to reproduce so he played the track aloud and it did wonders for the situation:

"We heard that there was a guy who couldn't get his horse to breed properly. He played 'Fix You' and sex took place. Now he has the most expensive stud farm in Britain."

Martin also opened up about being a musician with young children and joked that his kids, Apple and Moses, are a great platform to test out new material because if they like the music they will sing along to it all day:

"Kids are very honest - if they start singing a song it's because they like it. It's a great gauge. When we played Wembley Stadium I was like, 'Wow, now we are big rock stars', but next morning the kids were saying to me, 'Get me some pancakes.'"
