In October 2017, Taemin released his second Korean studio album, Move, and the title track gained attention for its distinctive choreography.

His third Korean studio album, Never Gonna Dance Again (2020), led by singles "Criminal" and "Idea", was widely recognized by critics as one of the best K-pop releases of the year.

[3][4] He joined SM Entertainment as a trainee with talent in singing and dancing and was chosen to debut as a member of Shinee in 2008 at age 14.

[9] On October 16, it was announced that Taemin, alongside Super Junior's Eunhyuk and Super Junior-M's Henry, Girls' Generation's Hyoyeon, and Exo's Kai and Luhan would participate as a six-member dance team for the Veloster theme song "Maxstep", the collaboration between SM Entertainment and Hyundai.

[10] In April 2013, SM Entertainment revealed that Taemin would be taking part in the reality variety show We Got Married with Son Na-eun as his partner, replacing the previous couple Kwanghee and Sunhwa.

[11] In the same year, Taemin made a three-episode appearance on the drama Dating Agency: Cyrano as idol singer Yang Ho-yeol with the stage name Ray.

The album contained ten songs, including the lead single "Press Your Number", which was co-produced by Bruno Mars.

[24][25] Taemin told reporters at a media showcase hosted by bandmate Minho at the SM Town Coex Artium in Gangnam District, Seoul, "After my EP, I did perform with Shinee but I also spent a lot of time preparing my next solo album, […] I took a lot of private lessons for voice and dance, and looked over my past songs.

[31] In July 2017, Taemin held his first solo concert in Japan at the Nippon Budokan in Tokyo,[32] attracting 28,000 fans.

[34] Taemin held his first Korean concert, Off-Sick, over three days at the end of August, playing to a total of 12,000 people.

[35] Encore Off-Sick concerts were announced on September 7 and took place on October 14 and 15 at Jamsil Gymnasium,[36] attracting 10,000 fans.

[40] The crime series, directed by Masatoshi Kurakata and Takeshi Maruyama, was an original Japanese work for Amazon Prime Video and released in September.

[42] His first reality series, The Taemin: Xtra Cam, was broadcast through V Live, showing preparations for his upcoming album and behind-the-scenes concert footage.

[45] Its lead single of the same name gained attention for its unique choreography and sparked a trend called "Move Disease" after a performance of the song went viral in South Korea.

[51] That same month, Taemin was scheduled to perform at the annual KBS Song Festival but pulled out a week after the death of bandmate Jonghyun.

The show saw him travel to Los Angeles alongside Eunhyuk and Highlight member Lee Gi-kwang in their quest to become choreographers.

[66] In August, Taemin debuted as a member of SuperM, a K-pop supergroup created by SM Entertainment in collaboration with Capitol Records.

[68] Taemin returned to Japan with his T1001101 concerts in December, performing at Yokohama Arena and Osaka-jō Hall over three days.

[69] Taemin was scheduled to hold a concert, Never Gonna Dance Again, in Seoul in March 2020, but it was cancelled due to the COVID-19 pandemic.

[70][71] Ahead of the release of his upcoming album, he starred in the online reality show Rare-Taem, in which he completed missions based on the results of a board game.

[83] Taemin's solo contract with SM Entertainment ended in March 2024, though he continued to conduct group activities with Shinee under the company.

His frequent use of androgynous fashion and make-up, especially since his 2017 single "Move",[89] has earned him recognition as a pioneer of the genderless performance trend amongst male K-pop idols.

[92][93] Taemin's discography is predominantly pop and R&B and occasionally influenced by rock, hip-hop, trap and electro, darker in theme than his work with Shinee, and sensual in character.
