How to make a Soundcloud link appear in thread title

You may have noticed that some threads have a Soundcloud link in the title, like this: -

If you click the button to create a new topic and then paste the Soundcloud URL into the thread title, it adds that link to the thread name.

For the example above, I pasted the link in the title field, wrote some text below and then changed the thread title to “Drone - MisterMaster”, but when I created the thread, it remembered the URL.

Although interestingly, I’m unsure how to remove or edit that link once it’s been posted.
