If you look at my influences, above, you'll see that pop isn't really my thing, but yes, that PSB track us a good song I'll have to give their playlist a listen. Similarly I thought The Sun Always Shines on TV and Take Me On could have made half-decent rock ballads, but as for AhHa, no.
I really, really don't like Aerosmith, but they did an album Honking on Bobo, which is first class. Dream On isn't bad, either.
My point being is that it's possible to recognise talent in bands you don't like. "oh, that's a great song, but I hate it", sort if thing.
I struggle to find that in Swift's repertoire, what I've heard of it, though.
Perhaps it's more the show than the music that appeals.
