I have no favorite and tend to listen across the board when it comes to instrumental classics. Yeah no Opera for sure. I cant see how anyone would like that stuff. I used to listen to classic rock but changed my music style greatly since I got older. I do listen to Christian music and classics. I really don't miss the rock like I thought I would. Don't drink or smoke anymore so I lost a few friends (or so called friends) along the way but I don't miss the lifestyle, music or the hangovers! lol
