It happens all over the world. Here in India the biggest blockbuster movie hits are usually the absolutely brainless action flicks (and I’m a fan of the genuine greats of this genre) with little acting and even lesser script. The example of marvel films has been given - they’re mostly trash. Some of the most profitable games are things like Call of Duty and Fortnite. When I was growing up the biggest musical acts (post MJ era) were BackStreet Boys, Britney Spears etc
Again it depends on perspective. If we’re talking about genuine excellence, you won’t find it in the above. But from a layman perspective obviously these things all do something well as they appeal to a certain need people have. So yes you absolutely can make a distinction between popular good and genuinely great. The logic of “Godfather popular hence great” and “Avengers popular hence great” is actually a terrible one that makes no sense because pieces of art are popular for different reasons and exist for different purposes. You cannot compare Justin Bieber’s ”Baby” or TS “Shake it Off” with the complexity of a Stairway to Heaven for example. Popularity should neither be an automatic seal of greatness or a denial of it. I’ve cited here many times that MJ was both insanely popular and insanely talented. Swift is anything but - on a musical scale she is closer to the bland generic artists just dialed to a 100 due to great marketing / relatability / packaging.
Not usually a fan of Indian cinema but I watched RRR with my wife the other day, loved it tbh and now we're watching this Netflix series called Kaala Paani which is superb as well!
On the music front though, I love Taylor's music (Not a fan of most of the new pop artists since the 2010s, aside from Taylor, Billy Eilish, Weeknd, a couple Dua Lipa songs, and Bruno Mars perhaps) and but I also listen to a wide variety of music that ranges from Pop, Oldies (60s - 90s), Classical, a bit of gangsta rap, deep house, new metal, old metal etc. Lately I've been listening to a bit of Thrash metal, a bit of classical, a bit of new age Synth wave, classic hits, and a bit of traditional fusion (Namely bands called Tinariwen and The Hu).
Would I pay to see Swift live though? No, I'd rather go watch bands like Guns n Roses (Saw them in Sydney some time back), Eagles (Also saw them in Sydney), Metallica/Maiden (some of my all time great bands that I haven't seen live) and the Hu (Also on my watchlist to go see live). That's nothing against Swift, I just prefer the atmospheres of rock concerts or EDM festivals or even a classical orchestra night to pop acts.
All from Taylor Swift, to Led Zep, to Megadeth are fantastic artists though in my book and I go to those different artists depending on my mood / what I'm doing - I quite like Shake it off haha (Not my favourite song of hers though), while Stairway is probably a top 10 song for me, but I'm not that into MJ/Madonna for example and prefer Taylor's music! I wouldn't say she's as naturally gifted as someone like a Whitney Houston, Dion, Adele, or Winehouse but I'd say you have to rank Taylor high up there when it comes to all time great solo female pop artists.
