e more than $2bn (£1.56bn), making it the most lucrative concert tour in music history
Taylor Swift fans have been warned they could face hours of motorway tailbacks if they do not leave for Tuesday's sell-out Cardiff show in good time.
More than 70,000 fans are expected at the American superstar's only single-date concert of her 152-night Eras Tour, which is at the Principality Stadium.
Some who went to Ed Sheeran's Cardiff concerts two years ago were caught in 15-mile queues on the M4 into south Wales - with a few missing the gig completely.
So Swifties have been told to expect severe delays driving into the Welsh capital and advised to use public transport.
Postcode data suggests Tay Tay's Cardiff concert will attract music lovers from a wider catchment than most Principality Stadium events.
One Ed Sheeran fan from Berkshire took seven hours instead of the anticipated two driving to one of his three 2022 gigs in Cardiff.
So anyone going to Swift's only Welsh date on her huge 21-month tour have been advised to plan ahead, travel early and expect delays.
Roadworks and rail engineering works in south Wales have been suspended to help fans attending the show.
But drivers have been warned traffic increases by about 15% on the already congested M4 around Cardiff and Newport.

Traffic Wales have said the motorway around south Wales is likely to be very busy and drivers are urged to check the its website before setting off to avoif a Cruel Summer.
"For those attending and travelling a long way, make sure you have your journey well planned," said South Wales Police Supt Arabella Rees.
Both Transport for Wales and GWR will provide extra capacity on trains in and out of Cardiff but warned rail services across south Wales would be very busy.
GWR, which operates mainline train services between Cardiff, London, Bristol and Swansea, said it would put on 10 more trains after Swift's show - adding a total of more than 15,000 extra seats - to help fans get home.
One fan who is preparing for delays and travelling to Cardiff by train is Swiftie Bella Thorn.
"We are planning for major queues and waiting time at the train station as we are coming from Bristol," said the 16-year-old who is going with her two sisters and a friend.
"We've never been to see her before and are all very excited about it. We have made lots of bracelets over the past few months and have coordinated outfits."
Cassie Evans, a 14-year-old who has had cancer, is also going to see her musical hero and hopes to get a hat that Swift gives to a member of the audience during her performance of the song 22.
"I’m desperately hoping to get the 22 hat," said Cassie, who is going to the Cardiff concert with her mum.
"I’m recovering from a four-year battle with relapsed leukaemia followed by a bone marrow transplant and have missed out on so much.
"I hope Taylor thinks I’m special enough to receive it after all I’ve been through.
"Listening to her music helped get me through the many long days and nights of my treatment and recovery at Cardiff’s Noah’s Ark Children’s Hospital where I used to chat to the nurses about our favourite songs.
"It would mean the world to me to be chosen to meet her and receive the 22 hat."
A full Cardiff city centre road closure will be enforced from 12:00 BST until midnight
Fans have been warned against parking in restricted areas around Cardiff or face a fine while organisers had said people shouldn't camp around the stadium.
There will be a full city centre road closure in Cardiff from 12:00 BST on Tuesday - ahead of gates opening at 15:00 for VIP guests and 16:00 for general admission - until midnight.
Police have told anyone heading to see Swift in Cardiff that extra officers - including armed police, officers on horseback and facial recognition technology - would be deployed so people can expect a "safe and welcoming environment".
"There will be an increased number of local officers who will be highly visible on foot patrol before, during and after the event," added Supt Rees.
"They will be supported by our specialist colleagues... to ensure that people coming to the city have a safe and welcoming environment."
"That's while sending a clear message to anybody who might be considering attending for the purposes of criminality that it will not be tolerated, they will be identified and dealt with."
The American superstar has already played three nights in both Edinburgh and Liverpool in the UK.
Then after playing Cardiff, the 34-year-old singer will head to London for three nights at Wembley Stadium on the weekend.
