Enya Ireland's wealthiest female performer despite not touring as U2 ranked third in Music Millionaires Top 50 list
From Sunday Times' Music Millionaires Top 50
Enya has not had a number one single in the UK in more than two decades, but that has not stopped her from landing a spot in the Sunday Times Rich List of music millionaires.
The Irish singer-songwriter - who achieved global success with Orinoco Flow (Sail Away) in 1988 - has amassed a fortune of £91 million (€115m).
She is ranked 28th in the Top 50 of music millionaires in Britain and Ireland, down three places from her 2015 ranking.
Between 2015 and 2016, Enya's wealth has grown by £1 million (€1.27).
Enya is one of the most successful folk singers of all time, shifting more than 75 million records worldwide. The only Irish musicians to sell more records are U2.
The star, 54, has had huge commercial success despite not touring and taking years between albums.
However, she has previously said in an interview that she believes keeping a low profile has been beneficial to her career.
"A lot of people know Enya the music, but they don't know what I look like or what I do, and I think that's really good for me and for the music as well," she said.
Ian Coxon, who has edited the Sunday Times Rich List for 20 years, explained: "She's consistent with her wealth... we're looking at wealth going over a number of years.
"Enya hasn't moved a great deal, she's only up a million this year but she's a well-established artist and over her career has sold millions of records. Once you've got the wealth you staying the list, it doesn't disappear.
"She's still performing and still producing records, and a lot of these established artists, their followers go out and buy their records so that's a guarantee of some income in royalties."
Meanwhile, Adele has been named Britain's richest ever female musician - but is one of only three solo women to make it onto a new list of the top 50 wealthiest pop stars in the British Isles.
The Hello singer is estimated to be worth £85 million (€107m), £35 million (€44) up from a year ago, putting her in 30th place on the Music Millionaires Top 50 list from The Sunday Times.
She is also ranked at the top of the Young Music Rich List of performers aged 30 and under this year.
"It is men that dominate the list, and members of male bands by and large," said Ian Coxon, who has edited The Sunday Times Rich Lists for 20 years.
"Adele is the exception. No woman has been increasing her wealth like Adele - she's even outstripping young male performers."
Australian singer Kylie Minogue is worth £55 million (€69m) and at position number 42.
Minogue is tied alongside Coldplay's Guy Berryman, Jonny Buckland and Will Champion, and The Rolling Stones's Ronnie Wood.
British Phonographic Industry spokesperson Gennaro Castaldo said: "We all want to see much stronger female representation in such lists to reflect the major contribution they make, but with Adele one of the world's most successful artists and the likes of Taylor Swift, Beyonce, Grimes and Paloma Faith also hugely influential in inspiring not just fans, but a whole new generation of female performers and songwriters, I'm optimistic that a shift is gradually taking place and that we'll start to see things change in future."
Sir Paul McCartney and his wife Nancy Shevell top the list once again, with a joint fortune of £760 million (€965m), which is up £30 million (€38m) from last year.
New York native Shevell has her own fortune in the form of a £150 million (€190m) stake in her father's trucking business.
Coxon explains: "McCartney has got an additional £150 million (€190m) from his wife but he's still worth £610 million (€774m) in his own right. I don't think ... anybody will catch him soon.
"We obviously include composers like Lord Lloyd Webber (in second position on the list with £715 million/€908m) and Bernie Taupin at the bottom (49th position) who writes a lot of material with Sir Elton John."
Irish rockers U2 share a worth of £500 million (€635m) landing them in third position, with Sir Elton ranked fourth with his fortune of £280 million (€355m).
The Rolling Stones - Sir Mick Jagger, Keith Richards, Charlie Watts and Ronnie Wood - have a combined fortune of £630 million (€800m), making them the wealthiest band in Britain and Ireland.
New additions to the list are former Beatles star George Harrison's widow Olivia, and his son Dhani, in sixth position with a combined family fortune of £220 millio (€280m).
David Bowie's widow Iman Abdulmajid, and his son Duncan Jones (from his first marriage), are also new with a joint family fortune of £90 million (€114m).
The amount is made up of money left to them in Bowie's will (£70 million/€88m), as well as their own personal fortunes and royalties from his music since his death.
DJ Calvin Harris has more than tripled his wealth since landing on the list in 2014 with a fortune of £30 million (€38m). This year he is in 27th position with a fortune of £95 million (€120m).
"Calvin is a surprise - he's so successful and gets paid so well," Coxon said.
"People get in fashion and have a great success. I don't know whether his success will continue at quite the same rate."
Apart from Adele, the likes of Ellie Goulding and Florence Welch both feature on the Young Music Rich List of performers aged 30 and under.
Ed Sheeran also features on the list, but has made the move to the Top 50 list for the first time, with a fortune of £45 million (€57m).
One Direction's four members - Harry Styles, Niall Horan, Louis Tomlinson and Liam Payne - are all in joint third position with a fortune of £33 million (€41m).
Former member Zayn Malik, who left the band last year to launch a solo career, is behind them with £30 million (€38m).
Coxon said: "Potentially if he (Malik) can follow the success he had with his first single and his first album, he may well overtake his former band members from One Direction.
"He's just starting a solo career so he could potentially climb up above them."
The Music Millionaires list is released ahead of the 28th annual Sunday Times Rich List which will be published this weekend. The full list charts the wealth of the 1,000 richest people in the United Kingdom and Ireland's 250 richest.
The list is based on identifiable wealth which includes property, land, assets and shares in publicly held companies, but excludes bank accounts.
