YES

**An opinion like this will always be subjective. But insofar as we can speak objectively about this kind of thing, ABBA are definitely a strong contender for the 'greatest pop band' title.** Pop music is a genre that can encompass many different musical styles but is basically focused on what generates the most popularity and produces the most hits. - ABBA have a ton of hits — they were pretty much at the commercial level of The Beatles at their height in the '70s. During the '80s and '90s they became 'uncool', but rather than fading out of the mass consciousness entirely, they became staples of [the gay bar scene] (https://www.out.com/music/2019/9/20/abba-credits-gays-their-return-music). Their music was celebrated for its declarations of freedom, joy and hedonism. - Then they saw another mass revival and were introduced to a whole new generation with the Mamma Mia musical on Broadway in the late '90s before spawning into a film franchise. ABBA's [decade-spanning popularity] (https://www.bbc.com/culture/article/20140415-why-are-abba-so-popular) is undeniable — only exemplified by all the hype around their recent comeback and upcoming tour. - They tick all the pop band boxes — catchy dance tunes, breakup ballads, even behind the scenes drama and heartbreak. While they may not have had the industry impact of bands like The Beatles, in popularity terms they were a phenomenon. Their longevity is especially impressive considering their career was launched on Eurovision. If you can't possibly be convinced that they are 'the greatest pop band of all time', you can't deny that they at least deserve a place in the front-running.
