Most streaming services offer streams that are less than the quality of CDs since CDs are uncompressed PCM. I don't know what compression streaming services use and most people probably couldn't tell the difference between them and CDs. Though, with CDs, you own the license forever, there's no DRM, and you never have to pay again. You can use the music however you want within fair use.
