Adele's 'I Drink Wine' was originally 15 minutes long.

The track from '30', the Grammy-winner's follow-up to 2015's '25', comes in at just over six minutes but the 'Hello hitmaker has revealed it was actually much longer and her record label told her it wouldn't get played on the radio.

Speaking to Rolling Stone magazine, she said: “[The label] was like, ‘Listen, everyone loves you, but no one’s playing a 15-minute song on radio.'”

The deeply personal collection documents her heartbreaking divorce from ex-husband Simon Konecki - with whom she has nine-year-old son Angelo - as well as tackling motherhood and fame.

The 12-tracker includes the acclaimed lead single, 'Easy On Me', and sees the star flicker between blues, soul, and pure pop balladry.

Three bonus songs are available on a Target exclusive edition of '30'.

They are 'Wild Wild West', 'Can't Be Together', and a duet of 'Easy On Me' with country superstar Chris Stapleton.

Ahead of the record's release, the 'When We Were Young' hitmaker responded to those who have said she should "shake up" her sound on the internet - and vowed to never change.

She said: "When the 'Easy On Me' snippet came out, I go online for, like, five seconds just to make sure the label have put it out properly and I see these comments … Not many, and it’s normally huge fans of other artists, saying: ?'Oh, when is she gonna shake up her sound?' Why would I shake up my sound? No one else is doing my sound, so why would I change it up?

"But I think what’s happened is [since] I got signed, up until my last album came out [ '25' in 2015], the way the industry has completely changed.

"There was still a record industry.

"There were still record companies, there were still A&Rs when I last released an album. What I do, and what I was doing, it was encouraged. There was a safety around it.

"I think, now, there’s, like, 300,000 songs released a week! Everyone’s worried that time’s going to run out.

"Their team is encouraging them to do everything now, now, now, just to make a mark.

"I’ve never been told to do that by anyone, I certainly wouldn’t do it if I was told to."
