The pop star doesn't want his biggest hit 'Angels' played when he is buried and has instead penned a requiem, a classical piece of music known as a 'Mass for the Dead', to be played to mark his passing.

When quizzed on which of his tracks he wants played at his funeral, he said: "None. For that occasion I've written a requiem. All on my own, without any help."

A Requiem Mass is used to celebrate the repose of the soul or souls of one or more deceased persons at funerals, while Robbie's hit 'Angels' was previously named one of the most popular songs to be played at funerals in the UK.

The Take That star has joined a list of musical geniuses by writing a requiem. Other composers to have created pieces include Mozart, Verdi and Faure.

The 36-year-old singer - who is married to American actress Ayda Field - knows people will find it hard to believe he could pen a classical piece of music and admits he finds it frustrating that people don't give him any credit as a songwriter.

He moaned to German publication ZEITmagazin: "People often assume I am only marginally involved in the making of my music, which makes me very sad. I feel underestimated because too many people think I only sing songs which have been written by much more talented songwriters.

"Maybe that's because I never play an instrument on stage, which people interpret as a lack of knowledge about music or the technique behind writing a song. What can I do? Should I install a camera in the studio next time I make a record so the world can watch in amazement how I write a song? Luckily my bank knows how valuable I am. For a lot of people I will still always be the clown from that boy band."
