If I remember correctly from this case at the lower level (this newspaper clipping is really short on details) the site in question was actually directly linking to the files in general.

Rather than linking to the site or page hosting the files, this site was linking to the actual MP3’s – in essence, using the other sites as remote storage.

From the users perspective, they clicked on the link, and the music either began to download or play. There was no visual indication there was another site involved.
