The Evolution of music has changed a LOT over the years, here is the difference in music from 1980-2019. 80’s Music was Disco, Heavy Rock, etc. the popular instrument in the 80’s was the Electric Keyboard, many Disco songs had Electric Keyboard. A lot of Rock bands had there glory days in the 80’s. In the 90’s the most popular type of music was Rap and Funky Music. The main thing in the 90’s was dancing really fast. In the 2k’s there were a lot of new signers and that was the start of pop. The problem with pop is that it will not age well when it’s 2050 I would rather listen to 80’s music that 2k’s. Currently in the 2010’s pop is like the only music now and it’s gotten bad. In my opinion my favorite years of music were the 80’s.
