At least 99% of all modern mainstream musicians with any acclaim are overrated, IMO. Genuinely great modern music isn’t the stuff you’re likely to hear on the radio.
I definitely agree, especially in the last few years.
I saw a very interesting video, arguing that the rise of TikTok is what killed pop music. Ever since Old Town Road became a massive hit due to its popularity on the platform, record labels have been demanding that pretty much every song needs to be “danceable on TikTok”; with a trap beat, gimmicky lyrics, and a general feeling of generic-ness. Indie music is the only genre where you can escape producers demanding that artists pander to ADHD-addled teenagers.
