The way I understand it is that the 14th song is not a banger, but a song put between well known, good songs, to boost its number of streams.

I’ve noticed it a few times, I was listening to something like “best of 80s” and a few tracks were from the same band that I couldn’t find any info about. So my guess was that the creator of the list put some of the songs they (or their friends) made, then those songs got millions of streams just because they were on that playlist even though they had nothing to do with the expected content. It’s either for the money or maybe PR to make an impression that the band is popular
