JR4 (or maybe 3) had a module that would check some database to make sure the song being uploaded was not an existing work. i.e. If you want to prevent people from uploading The latest Taylor Swift song, you would do a check.
I'm not sure if it checked metadata against an existing DB or if it included a list of blocked names.
Anyway,
Can you explain how it worked?
Is there anything like this for JR5?
