ELI5 How does the government track people downloading illegal music?

Also, if possible, please explain how they can track who is visiting sites offering illegal downloads.

They don't bother to track who visits sites that offer illegal downloads since it it too hard to know what they downloaded.

But bittorrent, one of the most common file sharing methods, requires the computers to connect to lots of other computers using bittorrent in order to get all the different parts of the file. It is easy to set up a computer that joins this network and look at what computers is asking it for parts of a file that is illegal to download.

Then they ask their internet providers for the name of the owner.
