Arguing matters of taste gets us nowhere. Arguing against one musical style is like arguing that red is better, than yellow, or than blue just because you like it. But that’s just taste, there’s no accounting for taste, no taste is better than the next and every older generation condemns the next generation’s music, none of which is valid.
It is a real testament to music though, that people get so vested in a style that they’re willing to put their hearts behind it and argue for it, that just proves how much people love music. So if you do love it, then defend it against the real threat against it. If you want to have your favorite taste in music then defend VARIETY against homogenization. That’s what corporate leaders want, they want to focus on a few formulas called “pop” music, they want to decide the direction of music, rather than having the artists and the people decide. I support variety in music. If you like your own taste in music, then I say go ahead and have it, and I’ll have mine.

There was good music is the 1980’s, the underground music was good, keeping the rebellion that Elvis did with his pelvis, that Hendrix did by burning his guitar, that Bowie did when he was Ziggy Stardust, the Ramones, Richard Hell & the Voidoids, the Sex Pistols, that the 1776 rebels originated with Enlightenment thought. It was the rebellious Reggae music that inspired the punk rockers. The recording studios and the night clubs supported variety, but the radio hasn’t. The “pop” music truly became the corporate music in the 1980’s decade, so it lost its heart, and its passion, it was music that didn’t speak to anyone, it was just there to make money. But the underground music rebelled against that idea lacking any human spirit inside of it. Please don’t ignore the underground music just because the corporates did. The rebellion then was sexual, was about free speech, was gay, was fully energized, was atheist, it was exciting and thrilling, it was new, yeah sure it was adolescent, but nothing is perfect. 
In the 1980’s there was Bad Brains, Bad Religion, Suicidal Tendencies, Kreator, the Cramps, Red Hot Chili Peppers, Fishbone, Pogues, Sonic Youth, etc. There were many styles of music then, that’s where rap originated to, rap was just party music when it began in NYC, not criminal, earlier than the 1980’s, Blondie rapped during Rapture[1:56], the rap which was never played on the radio, Fab Five Freddy appeared in the song who later hosted “Yo, MTV Raps”, and Sugar Hill Gang was in the 1979, Don Cornealius’ Soul Train played lots of good music on television in the 1980’s.
These underground bands the PEOPLE chose to support, these bands played what the PEOPLE wanted and the concerts were a blast, the PEOPLE loved the high energy rock ‘n’ roll, taking off all of the cultural chains, and all the fun of keeping the rebellion up, a taste of freedom from the false moralists who oppose the democratic morals of free speech, culture, and freedom of conscience.
The rock ‘n’ roll rebellion was alive and well in the 1980’s, not that the radio would play it.
And there were some pop music that did well too, not many, but there were some. Cindi Lauper have beautiful songs like “True Colors”, “Time After Time”, a cover of the Reggae style James “Sugar Boy” Crawford “Jock-a-mo/Iko Iko” song, the sexual rebel song “She Bop”, and she wore a newspaper skirt on her first album cover.
The Police and String took the Reggae idea, just as Punk Rock did before that, and The Police took their music to the radio. Today Gotye - “Somebody That I Used To Know” has a similar sound to what The Police made. Lionel Ritchie, Elton John, Billy Joel, all made quality music in the 1980’s. If you’re not aware of all this then condemning the entire decade is not fair, just based on the radio music. Its rare that pop music plays a really gripping good song, but they occasionally do with Joan Osborne - Right Hand Man (In the spirit of Dusty Springfield, and Janis Joplin, and the Blues.), Dido - Thank You... I saw Pink Floyd in concert once, they were amazing truly. 
Tragically, the underground music also includes the White Power bands, music that promotes war against minorities, and this music was separated from the other normal music that was meant for entertainment. That segment of the underground music has led to the shooting in Wisconsin by the true suicidal murderer Michael Page, I hear that he is part of that White Power sub-culture, which has always been kept separate from the normal underground musics.
