Can I write a CD of random songs - without access to streaming?

@grislybutter - Can you get a CD burner to transfer your playlist from your computer?

@wharfy I have a CD burner. My question is, where do I get quality files from?

You can purchase the files from places like Apple Music, bandcamp, and alike. Depends a bit of what music it is. Then you own the tracks and can burn away to your hearts content. Typically songs are about $1 so 1 CD is maybe $20 worth of music. You can choose amongst different file formats (WAV, FLAC, AIFF) for download. You may have to convert particular files to a CD format (WAV or AIFF) before burning. Then use any CD burning software. Burning a music CD is no different than burning a data CD, as digital music = data.

Thanks @oberoniaomnia 

I read that the Apple Music format is not suitable for CDs. I used to burn 100s of music CDs back in the 2000s. Is there a best service for the most formats?

Both Qobuz and HDTracks sell downloadable digital versions of songs that you can purchase in several formats and bit rates. You should be able to be able to then burn them to a CD.
