I grew up in the late 80s so i had the pleasure of growing up during what i consider the absolute high point of all time musical endeavor. It might have been from all the coke that was flowing into music in the 80s but who knows. Recent bands like fischerspooner, cut copy, goldfrapp, and ladytron have adopted alot of the typical 80s synthesized sound into their music with awesome results.
Here are a few songs of typical 80s sound that i think embody what is so untouchable about 80s music.
