When demographics change, so does the music. The fall began in 1993. Mariah Carey’s rise/overall career was the canary in the coal mine for me. Dr. Dre/Snoop. their mainstreaming of weed/gangsta rap and the decline in quality of rock bands in general , and of course record execs pushing their agenda all contributed.
There are a couple different of decent rock bands I enjoy, like Skillet and Switchfoot.
