In ALL of Pacs song he mentions the name of one of his other songs...Why does he do it? n if there are any songs that u dont think he does post up the names n ill check it out, idk for 100% but im pretty sure.
he doesn't in "Until The End Of Time", unless you count chance words like "fame" and "outlaw", or the OG chorus, where 6.9 says "better day" and "crazy".
I've always wondered if that's how Pac came up with concepts for songs, by just going through his own lyrics, seeing something that caught his eye, and making it its own song.
I don't know about him mentioning them in ALL of his tracks though. Off the top of my head, I'm pretty sure Hail Mary doesn't reference another song.
