A study has shown that the melodies of popular songs have gotten less complex over the years, especially since the 1970s and 2000s.
This change might be due to the rise of new genres like hip-hop and rock, which often use simpler melodies.
However, the researchers say that other parts of music, such as the way it's recorded and mixed, are getting more complex.
So even though the songs might be easier to sing, they're still using lots of cool sounds and effects!
