The UK's top music millionaires have been compiled for the new Sunday Times Rich List, which will be published at the weekend.
Topping the music list - as in 2013 - is London-based Ukrainian businessman Len Blavatnik, whose empire includes the Warner Music Group which was acquired in 2011.
He is estimated to be worth £10 billion, way ahead of nearest rival Clive Calder - the boss of the Zomba group of music companies - who is worth around £1.4 billion.
X Factor boss Simon Cowell did rake in a further £50 million over the past year thanks to his music and TV hits, according to a new wealth list.
The mogul has seen his worth swell to £300 million to put him in eighth place, boosted by a new deal with ITV for further series of The X Factor and Britain's Got Talent.
Former Beatles member Sir Paul McCartney remains in fourth place with his and wife Nancy Shevell's fortune said to be at £710 million.
Take That star Gary Barlow is now estimated to be worth £65 million - more than doubling the £30 million he held five years ago.
