I just realized that “Blue Flame” by LE SSERAFIM and “American Boy” by Estelle and Kanye West are harmonic twins.

My fiancé just pointed this out and now I'm spiraling. No hate. Some of you may be unfamiliar with the other song, but they are both great groovy songs.
That jazzy bassline and almost identical BPM… I even saw a mashup video of the 2 songs!
