Yeah but there are a lot of older people and le wrong generation types who would throw an absolute fit if you told them The Beatles were pop stars, let alone a - gasp - boy band.
The unpopular opinion aspect isn't because it's wrong (because it's 100% true and the only reason they weren't considered a boy band at the time was because the term hadn't really come about yet; The Beatles entire sound is 'let's get as soft and poppy as we can without edging out of 'rock' territory'). The unpopular opinion aspect comes from the fact that certain people will argue that The Beatles are a rock group and nothing else until they're blue in the face, because admitting The Beatles are a pop boy band means that they like pop and boy band music and they can't handle that.
Anyway, probably not an unpopular opinion here but among my sports fan friends, saying this would be blasphemy: the MLB season starting is going to end up as a disaster, and one that'll have repercussions for the 2021 season and beyond at that.
