Miller parted ways with Rostrum Records when his contract expired in January 2014. On May 11, 2014, Miller independently released his tenth solo mixtape, Faces. Colin Stutz of Billboard wrote that the 24-track mixtape "shows [Miller] introspective, ruminating over his drug use, fame and past." Pitchfork's Craig Jenkins called Faces his "most consistently honest and personal work to date". Miller later reflected on Faces, noting his drug-addled lifestyle while recording it. The second season of Miller's reality series Mac Miller and the Most Dope Family aired on MTV2 in mid-2014.
In October 2014, Miller signed a recording contract and distribution deal for REMember Music with the major label Warner Bros. Records. He chose Warner as it was "the most independent thinking" company he met with. Miller's major label debut, GO:OD AM, was released on September 18, 2015. It charted at number four on the Billboard 200, with 87,000 album-equivalent units. The album and the single "Weekend", featuring singer Miguel, were certified gold and platinum by the RIAA, respectively.
Miller began work on his next studio album immediately after completing GO:OD AM, wanting to explore the emotion of love. His fourth studio album, The Divine Feminine, was released on September 16, 2016. The album features Miller singing nearly as much as rapping, and incorporates genres such as R&B, jazz and funk. It received positive reviews, with Pitchfork stating that the album was succinct and refined in its portrayal of love, consequently accentuating Miller's artistry. The Divine Feminine debuted at number two on the Billboard 200 and number one on Billboard's Top R&B/Hip-Hop Albums chart with 48,000 units.
Miller's fifth studio album, Swimming, was released on August 3, 2018, to positive reviews from critics. Pitchfork described the album as consisting of "wistful soul and warm funk", through his exploration of heartbreak and his own mental health issues. Swimming debuted at number three on the Billboard 200 with 66,000 units, his fifth consecutive top five-charting album release in the United States. After his death in September 2018, the single "Self Care" rose to number 33 on the Billboard Hot 100, his highest peak as a lead artist at the time. Swimming was nominated for Best Rap Album at the 61st Annual Grammy Awards. Read more about Mac Miller’s life and career here.
