System Of A Down's 2001 track "Chop Suey!" has surpassed one billion plays on Spotify. The track's popularity on the streaming services isn't too shocking, given it's been featured in everything from the movie Sing 2 to a recent viral cover on TikTok… and about a million other covers over the years.
For reference, "Chop Suey!" is just over one billion plays. System Of A Down's next most popular song is "Toxicity" with 668 million plays, and then "B.Y.O.B." with 460 million plays. "Lonely Day" and "Aerials" are somewhere around 375 million, and the rest are under 200 million. So yeah, "Chop Suey!" is far and away System Of A Down's most popular song.
System Of A Down's Toxicity album (where "Chop Suey!" comes from) has sold over 6 million copies in the United States over the years, and over 1 million copies in Europe. The video for "Chop Suey!" is equally as popular, racking up over 1.2 billion views since being uploaded in 2012.
