Some of the best songs (to me at least) are songs about relationships between people. It's a topic that everyone can relate to. Whether it's about a relationship between a man and a woman, a boy and his dad, good or bad, etc...etc. So what are your favorites? BTW this isn't genre specific so throw out your best Wham! if you want.
I'll start it off. This song is about a relationship between a son and father. More specifically it's about the death of the father and the son's thoughts. This song came out about 15 years after my dad died but I still get some chills when listening to it.
