What is 4:34 am?

It is a song title by AfterTheParty. The song title inderictly implies the golden hour of "sad nigga hours" for AfterTheParty and his fans. Where they have thoughts about their partner or their ex-partner, as written in the lyrics "Don't you just leave me alone". Though it is not only restricted to him and his followers, it could just be a coincidence that someone is up during that time.
