True, take The Beatles. At face value it seems crazy that Don't Let Me Down, their 29th most popular track on Spotify, is their most viewed video/track on Youtube. IMO it's clearly the event and the live footage of it, the legendary and iconic Apple Records roof top concert, by the band, that's actually getting the views.

The song was featured in the Thor film. That soundtrack boost from Marvel is huge nowadays.

While I agree with you, that a song in a Marvel film helps give it a boost, November Rain has been one of the most streamed videos on YouTube for years, way prior to its inclusion in Thor.

What an amazing and successful band!!

It’s definitely because of the video.

It’s not that Sweet Child O Mine’s video isn’t good, interesting or entertaining, but November Rain’s music video, besides having a big budget/production, which means really good special effects/cinematography, it tells a whole story like it was a movie, and it’s also, as it shows at the end of the video, based on the short story “Without You”, by Del James, from his book “The Language Of Fear”.

Also, the song itself it’s arguably Axl Rose’s Magnum Opus, it was written before Guns N’ Roses even existed, and it was obviously expected that someone as perfectionist as him would use whatever was within his power (money, and a band full of talented musicians) to make the song a total success, and by the time he finally decided to share his beloved song with the whole world, he already had both.

Its success and popularity it’s very well deserved 🤘🏻💙
