There are a lot of songs that can bring a tear to my eye, for a lot of different. The one song that absolutely crushed me the first time I heard it though was Atmosphere - Yesterday. It still gets my emotions going every time. I love every song that you guys have picked so far!
I just listened to that song for the first time. And as wandering said, it's absolutely masterful lyricism. That said, I didn't even come close to shedding a tear. Not even close. I know the emotions and feelings he's talking about, but I've made my peace. And I'm not all that close to anyone anymore. Growing up, I lived around a lot of military families, and so most of my friends ended up moving away after a couple years of knowing them. Hurt every time. And over time I've clammed up. I imagine it's going to take a very special person to be able to make me give a damn about them. And I guarantee I'll cry my ass off if they leave. But other than that, I imagine that no matter who it is that leaves, I won't feel a damn thing. To this day there's really only one or two people who I really miss and want to get in contact with (but can't). Great song though. I really enjoy songs like that (lyrical raps with more emphasis on story than bitches/hoes).
The first time I heard that song was when I was driving in a car with my best friend after I had just found out my grandmother had dementia. The way he leads the listener to believe the song is about one thing when it is really about another...I don't want to spoil it for anyone who hasn't heard it, but it is masterful lyricism.
