Music appreciation

Maybe it's a sign of maturity (I said maybe), but within the last few years, I've been appreciating what some would call older people's music.
This morning, I sang out loud (I don't think anyone heard, thankfully) "Mamas, Don't Let Your Babies Grow Up to be Cowboys."
And, since Low Rawls' death, the line from one of his songs that goes "You'll never find ..." loops over and over in my head.
It wasn't really until just before his death that I started enjoying Johnny Cash. What pulled me in was the Trent Reznor song "Hurt" he re-did.
Often, I've been a fan of the big rock chords. Still am. I also enjoy much of the Christian music scene. But maybe I'm seeing a side of myself I haven't seen before and translate this willingness to branch out into other areas of life and do more risky things than simply listen to older people's music.
