I had a Tidal trial and was trying to see how encrypted their lossless music was. It uses some Chrome NaCL executable to decrypt, then play the music. In any other browsers, you cannot play HiFi music since they do not support NaCL.

That seemed like a good solution to DRM encryption.

At the end of the day though, people can just record the input on their sound card if they really wanted...
