Apple Music is not the same high quality that music in my Library with Apple Lossless Compression offers. Agreed.
I'm wiling to live some sub-par audio quality when paying for a monthly music subscription service such as Sirius or Pandora or Apple Music, with their access to essentially any artist and song I want.
Guess that shows two different approaches to music listening. You want to hear a particular song, and if it's a favorite, you can fill in the missing musical details for yourself. For me, if the instruments and voices sound true to life, I'll probably find something worthwhile in the music, no matter the song.
What I've heard form Sirius so far is a harsh garble that I just can't get past.
