A Hawaiian museum history display of music history is interesting.

In this presentation the display talks about the 1980's being the final years of vinyl records.  The short period of the 1990 was the period of compact discs.  The 2000 is the 21st century. With new technology in recording new music that focuses on native language.  

I think about the number of vinyl records, CD's and digital music that I have.  I often think about my personal history if when u started listening to a particular music source
