CSN are a little 'too' soft for me. Sorry!
Not everything's for everyone.
I'm a bit of an audio omnivore. Came of age in 80's and all "hard" as you say (Judas Priest, AC/DC, Motley Crue, Iron Maiden, Ratt, etc.) College was where CSN and some "softer stuff" came in. Now...I'm listening to Symphony now on satellite radio as I type this, and often the '40's channel (both of which surprise the hell out of me and I would have sworn would never happen when I was head banging). ...and yet I'm also still also buying Stones tickets and albums.
