Composition and lyrics
"Bottled Up" is a midtempo, R&B song that draws influences of tropical, reggae and hip hop music. It contains a "light tropical-tinged backbeat with a simple urban bassline." It runs for a total of three minutes and nineteen seconds. Lyrically, the song is about "drinking your feelings away" in an interview with Z100, she said "It’s about someone who has a hard time sharing their emotion, so they bottle up their feelings and they turn to smoking and drinking because that’s the way they’re getting it out." The song is in 97 beats per minute.
"Bottled Up" gained positive and negative feedback, mostly based on the songs sound, which had a very similar to Fifth Harmony's single Work from Home In an interview with "Music Choice" she explained saying "I remember being in the studio with Marc, and he was just like, ‘So what’s your vibe? Where do you wanna go with this? You wanna just make hits or do you wanna go global?’” Dinah recalled. “I was like, ‘I wanna go global. I want a global record […] I love this record a lot […] It’s been a year or two... and I feel like because it’s such a bop to me, it can be a bop to other people, as well.”
Thomas Bleech said that the "Chorus was way to simple" and that "not even a guest rap verse from Ty Dolla $ign could save this song and make it somewhat likeable or commercially ready. Mike Neid from Idolator said that "Jane gets a little flirty" and "Marc E. Bassy need a little coaxing to open up about their feelings." Matt Gehring from MTV said that they "Loved the 'Work from Home and 'Worth It' references" and that there "ready for a hit maker". HotNewHipHop called the song "Upbeat and high energy" and that it tackles "the subject of bottling up emotions in romantic relationships,"
