I don't know why, but compression sounds worse than any other bad recording type to my ears. I can deal with an album that's got a ton of pops and clicks for so much longer than compressed music.
Maybe its more the digital clipping than anything else.
For example, Metallica's Death Magnetic sounds respectable in my car. Through my iPod (lossless) and Etymotic 'phones, I can get through about 4 tracks. Through my home rig, I'm done after about 5 minutes. Its really too bad, because its a pretty good album.
I've got an old copy of The Wall on Vinyl. Its loaded with pops and clicks, yet I can listen to both sides without much complaint.
BTW, how come Pink Floyd never re-issued The Wall on vinyl?
