Just use the same cables that are used in the server farms of Spotify, Amazon, Itrax and the like to transport their digitized audio around their server farms and by all of the NSPs, NAPs, ISPs to then send it to your modem. These are mostly generic cables made in-house, Can you imagine how much music would cost if they all had to pay more than a few dollars for each of their housands of millions of ethernet cables.?
