In this season, a new feature was added where artists can choose to perform their original songs at any point in time, which extends the blind audition rules of
Sing My Song, a show that has been cancelled after 3 seasons. In this stage, the coaches are to recruit a total of five artists to form a team of their own, contrary to six in Season 3. The forming of the teams would move to a format that is similar to the "Six-Chair Challenge" featured in the British version of The X Factor but modified. Once a team is full with five artists occupying all the spots, the subsequent artists which the coach has successfully recruited would have to face-off with one of the five artists in the sing-offs for a spot in the team. The incoming artist may select any of the five defending artists to compete against in the sing-off, and both artists would each sing a new song and the coach would decide on the winner. The winner would be given the spot in the team. However, unlike Season 3, this season introduces the 'Save', where other coaches can save any losing artist from the sing offs (the same function as the
steals from The Voice). The coaches are given 10 seconds to save the losing artist for elimination. If one coach presses their button, he/she will be automatically on the new coach's team and if more than one coach presses, same as with the blind auditions, the artist has the opportunity to choose which coach they want. For defending artists, once they have won a sing-off against an incoming artist, they would receive immunity from the subsequent sing-offs and immediately advance to the next round of the competition. ; Colour key
