I see the early days of YouTube and AMV’s was like wading through a mountain of repetitive turds to find the diamonds.
Also in my experience, it didn’t feel like a trailer to anime or discovery of songs. Most of the videos all over YouTube in the early days were really Naruto vs Sasuke or Goku vs Vegeta to [insert popular rock song]. So any anime fan during those days knew about DBZ and Naruto, and anyone that listened to rock radio knew who Linkin Park, Breaking Benjamin, and Three Days Grace were. They were the some of the most popular bands in the genre in like 2006-2010
To me it just kind of soured my experience and made it feel like some low effort thing people threw up on YouTube for clicks. Going through several of those videos didn’t give me a good impression.
