use curl to download media files

I would like to download a music from a HTTPS website. Now they don't offer a specific download button, so I imagined using curl in Terminal. Sth like that:

curl -O https://urlhere

This normally works, but not in this case. Is it because of HTTPS being used? I can suply the actual url if it's needed

This is the message I get:
