Were The 1980s, the most dramatic changing decade for Top 40/pop music?

[Refractive Reflections]

It seems like in the 1980s decade, that every 2-2.5 years the sound was changing and evolving quickly because of the rapid technological advancements of synthesized sound. (Some popular examples are instruments like the Yahama DX7, the Simmons drums, and Roland TR-808/909.)

If you compare the songs from the near beginning of the decade (1980) to the end of the decade (1989), every popular genre of music seems to have been abruptly redefined/changed.

Here are some genre examples:
In pop music, in 1980, Olivia Newton-John had "Magic" and by 1989 there was Paula Abdul "Straight Up".


In dance music, in 1980 disco was just about dead, and had one last breath with Lipps Inc. "Funkytown", by 1989 house music just busted into the mainstream with Technotronic "Pump Up The Jam".


In rock music, in 1980 there was progressive rock and punk rock with new wave just starting. Pink Floyd "Another Brick In The Wall". By 1989, glam metal was in full force, but one band who wasn't that glammed up but still part of the metal movement was Guns N' Roses ("Paradise City")


In R&B, in 1980 the genre that helped make disco was trying to distance itself from it but it had a few elements to it. (Diana Ross "Upside Down") By 1989, New Jack Swing was in the beginning of its peak with Bobby Brown "Every Little Step".


In Rap/Hip-Hop, in 1980 the genre got any steam in 1979 with Sugarhill Gang "Rapper's Delight". By 1989, the genre (not all of it, but going further into it) became a hotbed for controversy with explicit content about sex, violence, and racism and found in 2 Live Crew's "Banned In The USA" and "Me So Horny".


In Latin music, in 1980 there's hardly a blip of it in the American Top 40 radio scene. By 1989, the latin music genre had taken a sizable portion of the Top 40 radio "pie" with Latin pop and Latin freestyle, with Gloria Estefan at the forefront ("Get On Your Feet"). (An example of Latin Freestyle: Sweet Sensation "Sincerely Yours" [1989])



(Phew LOL , sorry for the HUGE post but I wanted to give these examples a side-to-side comparison)

...So after seeing all of these huge shifts in every genre of music, do you think the 1980s were THE most drastic change for music ever for a decade? ...At least from a sonic perspective...?
