As an old rock and roll boomer I mostly enjoy the music even though there are some so so recordings. There are some exceptions of CD's recorded so badly that they are unlistenable. I have a CD of the Who's Who's Next which I love the songs on that is so poor that I cringe if I try to listen to it. I have no idea how they screwed it up so badly. Some of the Dead's soundboard releases also grate on me even though I love the Dead's music because I have better recordings of the same tunes.
Of course what is best is well recorded and well played music.
