At the circus, I would assume that they had a contract allowing them to use the music, but it also required them to make their best efforts not to allow recording.

Their best effort, of course, was to ask people not to record, and then they didn’t need to bother doing anything else.

You could check out FolderFort. Sometimes they have lifetime pricing. I paid something like $170 for 3TB lifetime.

They have SFTP access in beta.
