Same here. They even listened to music on my account when I was listening too so I have to stop listening. It drove me crazy. It had happened since July to September. The sign-in were in many different countries including US, Germany, Russia, Indonesia, etc.
After I changed my password, it still happened so I think they did't need to know my password to hack and listen on my account! Only until I signed out my account on all devices, it stopped but the shortcuts are still there and Spotify doesn't have any option to remove or delete those shortcuts although I've listened to hundreds of songs since then.
I also have an inappropriate image showing up on my playlist that belongs to an album with a song that was listened to 1/4 of the way through... Yet it shows up as my number one shortcut.
This is also for my business computer which popped up in front of my clients. I have listened to other albums and songs and still, this is still the first image that shows up every time I load up Spotify.
I just realised that "Shortcuts" has disappeared from my Spotify home screen. Which is good, I have enough "shortcuts" already in My Library if I need to access things that I WANT to access again, thus the need for shortcuts.
An idea though, why not directing the AI to make shortcuts based on users' library? That way, Spotify create shortcuts of things that matter for each user! If Spotify wants to make a suggestion based on a user's listening history, there is already "Made for you".
Also, the idea that a human person cannot override the machine thinking is merely demeaning. Similarly, the option for clearing undesired content from showing, such as in "Recently Played" should be an essential feature.
How about you forget about this extremely stupid little poll of yours and just implement it? I listen to a podcast ONCE and it's there forever? I can't get rid of it? Never listening to another damn podcast again. I don't want to see it in my shortcuts and have no way to remove them. STUPID! seriously considering cancelling over something so simple to implement. Vote? on something that's 2 years old? Give me a break!
