10. MetLife Stadium, East Rutherford, New Jersey
The home of football's New York Giants and Jets, the 2.1 million-square-foot, 40-acre MetLife went up on hallowed concert ground in 2010. It's next to the site of the old Giants Stadium (now torn down) in the Meadowlands Sports Complex – home to legendary Bruce Springsteen and the E Street Band shows beginning in the Eighties. Bruce finally played here last year (three shows, including one on his 63rd birthday), and so have Bon Jovi and Kenny Chesney. "Probably the best stadium for concerts in the country," says veteran New York promoter John Scher. At $1.6 billion, MetLife is reportedly the most expensive stadium in the world. But it wasn't funded by local taxpayers – the Jets and Giants themselves footed the bill.
Fun fact: Confusingly to everyone other than New Yorkers, the Mets have nothing to do with MetLife Stadium. (It's named after MetLife, the insurance corporation.)
