While this discovery is indeed disturbing, it doesn't make sense that they would be doing this without being able to make any money from the music that's available for download on their website. I suspect that they are probably using Audials One, which is a program that can be set up to automatically record five different streams of songs at a time from online radio stations as well as from Spotify and Youtube. I've owned a copy for years but have mostly used it to find and listen to various online radio stations from all over the world. It's a very powerful program that can also record streaming video. It has been consistently been voted the best program of its kind for years. Here's the link to their website:
