Listeners of the rock and guitar-based music station cast more than 50,000 votes for the inaugural chart.
Britpop group Oasis, fronted by warring Mancunian siblings Liam and Noel Gallagher, dominated the top 10.
Four tracks from the chart-topping band were voted into the Best of British poll, with ‘Don’t Look Back In Anger’ at number two, followed by ‘Champagne Supernova’ and ‘Live Forever’ at number four. ‘Slide Away’ gave them a fifth entry, at 16.
Oasis made almost as many headlines as records courtesy of the Gallagher brothers’ fractious relationship.
The band had eight UK number one singles and albums and sold an estimated 70m records before their split in 2009.
Northern bands dominated the results of the Radio X poll with tracks by Mancunians Oasis and The Stone Roses, Sheffield’s Arctic Monkeys, and The Verve, from Wigan, making up the majority of the top 10.
Liverpool’s The Beatles cracked the top 20 with ‘Hey Jude’ at number 13 and ‘A Day In The Life’ six places below at number 19.
‘I Am The Resurrection’ by The Stone Roses polled at number five, with Arctic Monkeys hit ‘I Bet You Look Good On The Dancefloor’ one place below.
Fellow Northerners Pulp, The Smiths, and Elbow also appear in the top 20.
The late David Bowie is one of two representatives from the south of England in the top 10.
The London-born star’s classics ‘Heroes’ and ‘Life On Mars?’ took seventh and eighth place respectively.
The Verve are at number nine with ‘Bittersweet Symphony’, while the top 10 is rounded out by enduring rockers The Rolling Stones.
The Londoners, who have just performed a historic free concert in Cuba, earned their place with ‘Gimme Shelter’.
Mick Jagger, Ronnie Wood, Charlie Watts, and Keith Richards continue to perform the song, which first appeared as the opening track on their 1969 album Let It Bleed.
Radio X, which launched in September 2015, also revealed how its presenters voted in the poll.
DJ Chris Moyles backed Coldplay’s ‘Viva La Vida’, while Vernon Kay chose the Sex Pistols’ ‘Anarchy In The UK’.
Neither song made the top 20.
