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."
