Recording streamed music off the internet onto C.D.?


I'm thinking about buying a c.d. recorder to record some music but I have some questions first.  I would be buying it mainly to record music off of an internet radio station that I would not otherwise have access to (dj sets with no track listings...).  The thought of having a c.d. recorder brings me to another question though; if I were to record m.q.a. tracks straight from Tidal, why would they not be high resolution?  And lastly, what are the laws regarding recording music off of a site that you've paid to have access to?

I record orchestral concert streams from my Cambridge CXN. I use the analog output feeding a portable Edirol recorder, then take the memory card to my computer for a little processing. The Edirol has the ability to record 24/96, but I don't bother going that high because most of the streams are 128-192 bit mp3 streams. I can stream Tidal to my CXN, so I guess I could record their MQA at 24/96, but yes that would be illegal. Your recordings to a CD player would top out at 16/44, as that is the resolution spec for CDs. That's why they wouldn't be high rez.
Thanks for the feedback!  I'm not wanting to do anything illegal so I'll send a message to the radio station that I want to record and ask them what there take on it is...  I could see how recording tracks off of Tidal might be wrong (how much does the actual artist make from Tidal?  And Jay Z has plenty of $ already...) but I'm not sure if the radio station that I am trying to record cares; I'll keep you posted.  Also, my take on it is, there is no way to purchase these dj sets but if I recorded them and found new artists that I like I could then go and buy any music that they do have for sale, as well as promote their music to friends who have similar tastes... seems that that would be beneficial to the artists, no?  
From my own experience in recording streaming music, a screen recorder for computer is good tool that can be used to do that. With it, I can switch the audio mode to record system audio and microphone sound in flexible way. Most imporatntly, I can specify the output format configuration, including bit rate, sample rate, channel, etc. If record video, resolution can be customized as well.
