@pyruvi I moved your post over to this existing thread: How to clear all of my Liked songs
Unfortunately, there isn't an easy way to clear all of your liked songs all at once.
You will need to go into each of your stations and one at a time to remove your Thumb ratings.
Alternatively, the quickest way to start fresh would be to delete your account completely, and then create a new account using the same email address.
That way, you can start over again with creating new stations without having to manually delete the old thumb ratings you've given in the past.
I recommend upvoting this feature request with a ❤️ to express your interest in seeing it added to the service: "Soft" Account Reset
Hope this helps!
