@leocg It did not work. In this example I tried searching "heartless", but instead I got what you see in the picture. This is the case with everything I search. image url)
Instead, I tried " https://open.spotify.com/search/%s " and that worked. My problem earlier was that I hadn't understood what they meant by "URL with %s in place of query", but your example helped me. So, thanks! Have a nice day.
