The real music will always defend itself, no matter what decade, but generally when people talk about terrible 80's music they don't talk about cold wave, new wave, post punk, gothic or even superproduced pop. They talk about matrix made rubbish:
- mass manufactured tabloid SAW British pop = Stock, Aitken and Waterman productions - think early Kylie, Rick Astley, Jason Donovan, Pepsi & Shirley, every song exactly the same, every rhythm, sound, instrument exactly the same, every melody the same, all terrible, flood of rubbish, at some point there was like 50+ artists going at it in the same time, all exactly the same. Douches even organised their own Band Aid II in some shed. Soooo bad..
- mass manufactured tabloid Hansa EuroPop = Hansa Records & Dieter Bohlen - think Modern Talking, CC Catch, Chris Norman, Bad Boys Blue, Sandra, Blue System. Every song exactly the same, every rhythm, sound, instrument exactly the same, every melody the same and terrible, every chorus in falseto, engrish all over the place, flood of rubbish, at some point there was like 20 artists going at it in the same time, all exactly the same.
- American mass manufactured boyband tin foil L.A. hair "metal". Think Quiet Riot, Poison, Cinderella, Europe, Kixx, etc, by extension of hairdresser's chair often also stuck to Def Leppard, Scorpions, early Bon Jovi. Perms, spandex, lipstick, Kramer guitars in all shades of high-visibility jacket yellow, orange or pink. Steel Panther, but for real. Minimal distortion, catchy chorus ad infinitum, maximum hairy torso.
- Yo! MTV Raps. The moment music died. 1988, when MTV Europe stopped being a balanced servings of delicious sweetness. The year it stopped being about VJ programmes: Paul King's "120 minutes", Kevin Seal's "Headbanger's Ball", Ray Cokes "Most Wanted" or Simon Angel's "Party Zone" and started bombarding the air with never ending playlists of bad beatboxing, "ahem ahem" "hey, ho, hey, ho" and "sup, whaaaaaat" gangsta bruva's from private schools 24/7/365. But that's more of a 1990ies story.
