Yes, as a matter of fact, you can now use the box on top as search keywords receptacle, so if you submit anything that is not a properly formatted URL (https://website.com/path) - it will be treated as search request and we will try to find it on Soundcloud. Up to 50 first results will be shown to you, so if you can't find the song you're looking for - try to change keywords somehow more appropriate, include artist or anything else youi know about this song.
