I think the notion that it's the worst piece of software is a bit of a stretch here. I've used various streaming music players and Spotify has been the best by far. Doesn't mean it's perfect.

I get that not all edge cases (eg swipe gestures) are bullet proof but that doesn't make it terrible software.

It's objectively really bad at a lot things. I've always had the feeling that the music is not even a primary feature of their product.

The last time I used it, I uninstalled once I realized that my kids could watch Logan Paul YouTube videos through the Spotify app. These masquerade as podcasts, but like a Trojan horse they are just vods of YouTube content. And at the time there was literally no way to disable this. No way to either turn off podcasts or specific content through parental controls or otherwise.

I just wanted to give my kids a way to listen to music while reading. I have since switched to our local community radio station.

WinAmp was smaller, faster, and more customizable thirty years ago.
