It was certainly 'Golden Age' for polish bands.... Lady Punk, Banda i Wanda, Lombard, KAT...What we have now is mainly crap...
As for foreign pop/disco bands (A-HA, Sandra. Modern Talking, Madonna etc) - I still enjoy their music but in comparison to nowadays’ pop/disco music they seem to me more like soothing and calming music for old farts not energizing, fast music I remember from the past :-)
Same for Germany. The New German Wave in the early 80s was awesome. Most German music today is basically white-trash hip-hop and R'n'B, and pointless emo rock with lyrics that make absolutely no sense.
There are a few great exceptions. Everyone knows Rammstein. Die Ärzte are still awesome. Böhse Onkelz are good at what they do, never really been able get into their music though.
Although there has been a bit of a schlager revival of late. Not really my thing, although I grew up in the countryside listening to it at parties.
