Would you like a hot toddy with your blanket statement? ;\) That's an unfair assessment of many quality titles available in those eras, especially the 70s and 80s. Sure, a lot of material was recorded and/or mastered poorly, but there are many gems to be found. Pink Floyd and Dire Straits are only a couple examples.
