Didn't see a thread with people posting what songs meant a lot to them, so here's a few of mine.
Tracy Lawrence - If the Good Die Young
It's been true so far, but just in case...
Tracy Lawrence - If I Don't Make it Back
And one more, awesome song that never fails to do the trick, especially listening to it at midnight in the dark on vinyl. (Yes, I do have Boston on vinyl.)
Boston - More Than a Feeling
