It's really hard to totally pin down the exact number of KISS listeners because they have such a long and rich history and have had a massive influence around the world. However, according to their official website, they have sold over 100 million albums, which are a great indicator of their fan base.
KISS remains one of the most recognizable and iconic rock bands in the world. They have been around since the 1970s, and through their unparalleled melding of narrative lyricism, showmanship, and irresistible beats, they have attracted legions of fans. This includes their many world tours, multiple hit albums, dedicated fan clubs, and of course, their signature makeup and matching outfits.
KISS has millions of fans around the world and, in 2018, their official Facebook page alone had over 8 million followers. This, alongside their various social media channels, is testament to how much of an impact the band has had, and a clear example of their widespread popularity.
In conclusion, it’s very difficult to determine exactly how many listeners KISS has, but we can safely guess that it’s in the millions around the world. Their official Facebook page alone attests to the band’s global appeal and almost forty-year-long history in the music world.
