I like some country music, especially The Nitty Gritty Dirt Band( I know, some of their stuff is a little bit more rockish.). I think that Martina McBride and Vince Gill have good voices. Some of the older stuff (like Hank Willams Sr.) is okay as long as it's not to twangy.
I would have to say that "Never Say Goodbye" by Bon Jovi (off their "Slippery When Wet"album) really brings back memories of my senior year of high school (1987): enjoying still being a kid and not having too many adult resposibilities; having a crush on a guy and not knowing if he likes you back; a younger kid dying in a car accident; sitting on a swing at the playground after graduation and wondering what comes next.
