There is a few I could say like Mumble Rap or Dubstep but I am going with modern pop music, for multiple reasons. You just need to do a quick Google search to find many website articles, videos, posts etc...saying why modern pop music sucks to know this is true. Here are 4 of my reasons why I think modern pop music is bad and should be erased.
1. Lyrics. It seems some songs today have many writers to write ONE song (I don't know if there are older songs that had many writers but I know there are modern songs that do). Modern songs to me don't have lyrics that sound amazing, powerful or rememberable like many songs from the 50s to about 2010. It often feels like the lyrics writers are playing it safe and the song writing process has become too commercialised as they are writing songs they know will sell and appeal to social media algorithms, rather than taking chances and experimenting and coming up with something unique. To me, songs today are becoming more homogeneous and there is less variation in pop music than there used to be.
2. It feels to me that with some modern artists today, it is more about their persona and celebrity status than them coming out with great music.
3. Autotune. Some songs have that noticeable autotune sound I hate. Not only that, I feel that many songs today are too autotuned for that perfect pitch, which I think loses something as a lot of the greatest artists existed before autotune and they sounded great without it. I think one reason for the autotune being used a lot is that music producers and artists don't want to spend the time to do multiple takes to get the best one as it costs time and money, they just might do a few, take one and autotune it.
4. The backing tracks are usually not good sounding to me. They often have crushed dynamic range and often to me sound too digital and computerised such as lack of actual real instruments, its often samples, keyboards and computer generated instruments. Sure there were many songs in the pre 2000s that had mostly keyboard/synth or computer generated instruments like 80s Synthpop, dance, trance etc... but they don't sound the same as the modern sounding backing tracks do. While I don't know for sure why I think this, I think it is partly to do with a lot of music pre 2000s not having crushed dynamic range like many modern music does.
