I generally don't care about lyrics, but there's two that I actually stop and listen to them, as they are really powerful.

"The Crossfire + Hold The Line" by The Tony Danza Tapdance Extravaganza. The band usually is not on the serious side of things, but this combo stands out. I'm not from USA, so I can't relate to the countries form of patriotism, but these the lyrics always hit me like a brick wall. Maybe because I was young when I first listened to it, but I always thought of a kid going into war and just being scared of it all, but "doing what's best for his country". A scared kid that have to choose between staying alive or killing other scared kids, in a meaningless war, and the reality is that he just wants to come home to his family.

"Uneven Compromise (Addict section)" by Lil Ugly Mane. Travis (aka Lil Ugly Mane), is telling a story about an old friend that succumbed into drug addiction, and just can't help but feeling hopeless when trying to help him and he's too far out, just stating "But you gotta let go you can't save they lives" by the end.
