I also lean toward country, but I'm finding that I now enjoy more of the Rock and Roll from my youth that I didn't enjoy at all back then. Grew up in the 70's sticking to hard-line Outlaw Country, Willie and Waylon, Merle Haggard, Johnny Cash, Kris Kristofferson, Hank Williams, Jerry Jeff Walker, etc...
Now I'm also enjoying Bob Seger, CCR, Feetwood Mac, Billy Joel, Foreigner, even some AC/DC and Queen now and then.
Still can't tolerate any disco, and never did learn to appreciate any rap music.
I have a 7-year-old grandson, and I've told my son that the thing I'm looking forward to most is when his son starts listening to some new kind of music that he can't stand.
