It does say &quot;on a commercial scale&quot;, so it has to be big. However, I think using bittorrent counts since you are offering to upload the file to anyone on the internet who asks for it. Just singing it at a single private party wouldn&#x27;t be included, but a restaurant chain singing it for every birthday party would.<p>Not sure what &quot;prejudicial impact&quot; means, but it&#x27;s probably something that would keep people from buying the copyrighted version.
