• "Mood Swings" is a song by American rapper Pop Smoke featuring rapper and singer Lil Tjay,
released on July 3, 2020, as track 13 from Pop Smoke's posthumous debut studio album, Shoot for the Stars, Aim for the Moon.
• Pop Smoke and Lil Tjay previously collaborated on the tracks "War", "Mannequin", "Mary Jane" and "Zoo York", the latter from Lil Tjay's May 2020 EP State of Emergency.
• Pop "effortlessly" raps about having sex with women off their birth control, while issuing them a reminder that he is not interested in a relationship. Arguing that the song is certainly "not romantic", Alphonse Pierre of Pitchfork described it as "being pushed as a sweet-sounding love song with an edge, which seems about right, until you get to the unsettling lyrics".
• "Mood Swings" reached US Billboard Hot 100 no. 25; US Hot R&B/Hip-Hop Songs Billboard No. 19; and US Rolling Stone Top 100 No. 9.
