If you listen to a 50s song, you know it's a 50s song. If you listen to a 60s song, you know it's a 60s song. The same if you listen to 70s, 80s, and even the 90s. However, if you took a hit song released in the late 90s and early 00s and released it today, it wouldn't sound out of place on the radio today, in the 2020s. There are talented artists today, but shit has not evolved. Its stagnant.
