Researchers at the Spanish National Research Council recently conducted a study, which determined that much of today's pop music is louder and sounds the same.
The research team used the Million Song Dataset, an archive, to analyze tunes from 1955 to 2010. They concluded that pop songs are louder and more bland, today, when it comes to arrangements of melodies and chords.
Artificial intelligence specialist Joan Serra told Reuters: "We found evidence of a progressive homogenization of the musical discourse. In particular, we obtained numerical indicators that the diversity of transitions between note combinations, roughly speaking chords plus melodies, has consistently diminished in the last 50 years."
The study, which appears in the journal Scientific Reports, claims that old songs re-recorded louder, with simpler chords, but different musical instruments, could actually sound new.
Maybe that would explain why Lionel Richie's re-recordings of his old tunes on the 'Tuskegee' CD have become so popular?
