Media mogul Simon Cowell has leapfrogged stars such as Sir Elton John and Sir Mick Jagger to rocket into the top 10 of music millionaires.
The X Factor and Britain's Got Talent boss has seen his wealth soar by a further £35 million in the past year, according to the Sunday Times Rich List.
Cowell's £200 million fortune places him at sixth in the list of British and Irish millionaires to be published this weekend, just one place behind his old friend and rival Simon Fuller.
He is still £175 million behind Fuller, the man behind TV shows Pop Idol and American Idol, which set Cowell on the road to TV stardom.
In the past year Cowell - boss of production company Syco - has signed a new deal with ITV and is also preparing to launch a US version of The X Factor.
Earlier this week he announced plans to launch a new gameshow fronted by Ant and Dec called Red Or Black? and has talked of launching a global pop show in the future.
Clive Calder tops the UK music millionaire section of the 23rd Rich List, with a fortune of £1.3 billion, made from the sale of his Zomba Records in 2002.
He has regained his position at number one after the 2010 chart-topper Edgar Bronfman moved back to New York from his temporary home in London.
Lord Lloyd-Webber is second in the list with £680 million, while impresario Sir Cameron Mackintosh is gaining fast in third place, only £5 million behind at £675 million.
Sir Paul McCartney is ranked fourth.
New entries to this year's top 50 include AC/DC singer Brian Johnson who is estimated to be worth £50 million, according to the list compiled by wealth expert Philip Beresford.
He is ranked at 42, jointly with Sir Cliff Richard and Van Morrison.
The highest new entry at 34 is claimed by Moya Doherty and John McColgan, who own the Irish dance show Riverdance and are said to be worth £70 million.
Noel and Liam Gallagher are listed together with a joint wealth of £63 million despite their high profile fall-out which saw guitarist Noel leave Oasis in August 2009. Liam has since relaunched his career with Beady Eye.
