WatchMojo is just a site/youtube channel that makes a bunch of top 10 lists.
Anything to do with music, movie, tv, games, politics, pop culture in general etc. They're not a "serious" channel by any means, really, but if you're not careful you could watch one video and then somehow end up watching 5 more or something. I've done that before.
But yeah, I rewatched the video where she talks about Intuition for the Greatest Hits album, and she's right. Nowadays you see so many newer artists who by the very definition "sell out" from the getgo and teens/early 20-something fans don't seem to care as much.
Rewatching the Intuition video itself makes you realize that it sort of was ahead of its time spoofing the whole sponsored products in music videos thing, even though no one knew that would actually become a thing!
Britney's Hold It Against Me is just one blatant example.
And I actually like the intro to Avril's Rock N Roll just because they play it up to how ridiculous it is.
