Singer (season 4)

An online Spin-off of the show, I Am a Singer- Who Will Challenge (我是歌手—誰來踢館) was aired daily from 5 December 2015, until the finale on 23 January 2016, on the online site of Mango TV, for a total of 50 days.

The site featured each contestant having their own Challenge page, where online viewers were able recommend the singers in participating the competition. When a singer's recommendation hit at least 18,000 views, they were eligible to participate in a daily live show aired between 5 December 2015, until 7 January 2016. During each episode's broadcast, viewers could distribute their 100 "Decibel points" to the singers they liked the most on each show.

The top eight singers accumulating the most 'Decibel points' after 7 January moved on to the Sing-off. During each night's broadcast until 15 January, two random singers had to sing one song each, with a total of three songs throughout the eight shows. 10,000 viewers were be chosen at random. These viewers distributed their 100 "Decibel points" to determine the contestants placement in the sing-off as well as in the finale. The second week's shows that aired from 16 January until 22 January featured the singer's daily lives and their preparations up to the finale.

The finale aired 23 January and showcased the eight singers for the last time, each singing two songs (one chosen song and one hit song from previous seasons). In each round, 10,000 "Decibel points were distributed to random viewers eligible to cast their votes for the winner (viewers had to vote for three singers to be counted as a valid vote). The singer accumulating the most votes after two songs would win the right to take part in the competition as a Challenger on the third Challenge round.

Korean singer Kim Ji-Mun was named as the winner of I Am a Singer- Who Will Challenge.

A tiebreaker can occur when multiple singers were tied with the lowest votes cast during an elimination round. The tie is resolved based on the placements in the next round, and the singer receiving a lower placement (regardless of the placements from other singers) was eliminated. Any eliminations (if applicable) in the following round would conduct as normal.

Coco Lee later returned as a guest performer on the fifth and sixth seasons. Kim Ji Mun later appeared on the seventh season as a guest performer for Yang Kun. Lala Hsu returned to compete for a second time on the eighth season.

Four of the six singers who were initial singers (Hsu, Hwang, Coco and Hacken) were exempt from this round, while the other two singers participated along with previously eliminated singers for a chance to enter the finals. The performance order was determined based on the contestant's status quo and their duration on the stage. All but four singers went through ballot to decide the order, while Chang and Yung selected their performance freely, while unsuccessful challengers (Su and Kim) were defaulted to the first two performances.

The singers sang one song, and the three singers with the most votes qualified for the finals. Chang, Yung and Lao were the top three singers who received the highest number of votes and advanced to the finals. In a final tally, Lao, Wang, Shin, Kim and Su were revealed to have garnered 142, 134, 100, 99 and 98 votes, respectively.

"我的天空", during Chang's performance as part of his medley, was edited out due to time constraints. This is currently the only episode to date in I Am a Singer where all participating contestants in the Breakout round doubled their roles as the hosts.
