His 2010 single, "Down on Me" (featuring 50 Cent) saw continued commercial success and matched the chart position of "Birthday Sex", also receiving sextuple platinum certification by the Recording Industry Association of America (RIAA).

He formed the duo MihTy with singer Ty Dolla Sign in 2018, with whom he has released an eponymous collaborative album (2018).

[6] Felton was a good student and earned academic honors at Morgan Park High School, allowing him to graduate a year early.

[12][13] After performing a tribute to Ray Charles at one of the campus's talent shows, he received positive feedback and realized his vocal ability, saying that the "music was just taking over".

[16] In February 2009, Jeremih met with Def Jam's CEO Russell Simmons, and executive vice president of A&R Karen Kwak.

[19] In promotion of the album, Jeremih took part in America's Most Wanted Tour, alongside Lil Wayne, Young Jeezy, and Soulja Boy Tell 'Em.

[22][23] Community activists protested and demanded CPS to undo their decision, claiming that Jeremih's music was "not appropriate for students" and "promotes teen sex".

[23][24] Huberman argued that "school officials would be naive to pretend students don't listen to Felton's music already".

[23] In September 2009, Jeremih performed on ABC Daytime's soap opera One Life to Live, alongside recording artist Lionel Richie.

The following year, Jeremih and Rick Ross were featured on the song, which was performed by Wale, titled "That Way" from the compilation album Self Made Vol.

Members of Jeremih's crew responded to the alleged racism by taking over the restaurant's microphone, throwing beer onto employees, and allegedly throwing a glass beer bottle into the kitchen, getting broken glass into the fryer and forcing the restaurant to close temporarily.

[5][permanent dead link‍] "All the Time" is a song which originally appeared on his mixtape Late Nights with Jeremih but was re-released with an additional verse by rapper Lil Wayne as a single.

He co-wrote alongside his voice imitator The Weeknd and Travis Scott Rihanna's song "Woo", from her January 2016 eighth album Anti.

[41] In July 2016, Jeremih released his second mixtape called Late Nights: Europe, which he recorded while on tour overseas.

[51] Pitchfork stated, "When his projects are well-considered, or made with hyper-focused collaborators, he can be the most enchanting man in the room," but called one of the four tracks awkward and bored.

[52] On June 8, 2018, Jeremih and Ty Dolla Sign released "The Light" as the lead single from their collaboration album MihTy.

[53][54] The 11-track album was released on October 26, 2018, and features guest appearances from Chris Brown, French Montana, and Wiz Khalifa.

[61] In April 2023, he introduced his first protégé, Illinois singer Murf Dilly, to the music scene with his debut single "2 C's".

The song featured Jeremih as a guest vocalist and was released on his newly established Late Nightz Records.

[65] With the release of his debut album, Andy Kellman of Allmusic compared Jeremih's vocals to Slim of R&B group 112 and Raphael Saadiq, noting that his "charmingly sly voice...is hard to not like".

[14] In contrast, Ken Capobianco of The Boston Globe felt that Jeremih's voice was "thin", showing "little range".
