Personally, music has been mostly in decline, especially since the advent of trap music and its subsequent hogging of the Hot 100 from around 2018 onward. But there has been some recent acts out there from about 2016 onward. Hits like "Havana", "Cake By the Ocean", "Feel it Still", Circles", "Good As Hell", "Señorita", "Don't Start Now", hits by Maroon 5, Doja Cat, Harry Styles, Ed Sheeran and others have added much-needed variety to the music scene, seemingly over dominated by trap artists album bombing the Hot 100 with filler songs that fall off after one or two weeks.
I realize trap style music is popular among current demos, but it cannot be the only genre to dominate the Hot 100. Not everyone likes that genre. Many like recent pop, dance, rock / alternative or even some contemporary music by Adele and Olivia Rodrigo. It's refreshing to hear Sir Elton John come up with "Cold Heart" in collaboration with Dua Lipa. Bruno Mars has gone retro with "Skate" and "Leave the Door Open". The Weeknd have provided the Hot 100 with some hope with their amazing longevity in the top 40 with mega hits "Save Your Tears" and "Blinding Lights", first introduced in late 2019.
The current #1 song is "Heat Waves" by Glass Animals, an appealing song introduced on the Hot 100, 61 weeks ago! And a British act, hopefully this trend continues, in comparison to the late 2010's, where the charts were stagnant with a single genre of music. Remember "Old Town Road" by Lil Nas X in 2019? NINETEEN weeks atop the Hot 100?? I just don't get it.
Overall, I tend to prefer the 2010-2014 period a bit more, with an exception to 2017 as Camila Cabello's "Havana" and Portugal the Man's smash provided something really special that year, which unfortunately did not last long.
