Hey there and welcome to the community!
Hmm.. That sounds weird. Spotify doesn't automatically add songs to the queue. Is it possible you may have slid across the screen? Like in the screenshot. That gesture adds a song to your queue. If you didn't do this just let me know by replying here in this thread.
Good luck and have a nice day!
No problem, we're always happy to help! Have a nice day! 🙂
