In bygone years, the BBC Two's selection show You Decide has featured six acts all performing a different song each before the best is selected to represent the UK.
But this time there will be just three songs for the six acts to sing, meaning they'll go head-to-head to see who can do the same song the best.
Each of the three songs will be performed in two musically different ways by two acts, and there will be three rounds of 'song-offs' in the show, which is hosted by Mel Giedroyc and Mans Zelmerlow.
Kate Phillips, controller of entertainment commissioning at the BBC, said: "Forget about a sing-off, next year it's all about the song-off as we once again try to marry a great singer with a great song, one which could finally get us on the left hand side of the leader board.
"We may be leaving the EU, but we are still determined to win Eurovision again one day!"
You Decide will be shown on BBC Two in February 2019 ahead of the contest, which takes place on Saturday, May 18.
