I listen to Pandora most days when I'm driving back and forth across the country. A lot of my favorite songs from the '60s and '70s, they play the "remastered" versions. I always looked at remastered as getting rid of the background hiss and whatnot that you heard when CDs first came out in the '80s.
What the final product seems to be.l is there more tinty and there's a bunch of reverb at it. I can't think of the single one that sounds better after they finish with it
