Old Music - Better Produced?

[thehawk]

So I've been listened extensively on Spotify to a wide range of music from the 70's and 80's - it just seems to be much better mixed/produced. Things such as strings seem a lot more acoustic (natural?) and less processed. Easier to pick out individual instruments and generally nicer sounding timbres.

Compared with a lot of later stuff today that just seems a bit mushed up, not as clean and too processed.

Am I alone in this or is there a good reason?
