Here's a great one:
War's "Why Can't We Be Friends"
This is a rough outline of a video set to Steven Universe clips:
"I've seen (sic) you 'round for a long long time" = Steven and Amethyst hanging out, snacking
"I've seen you walking down in Chinatown, I called you but you could not look around" = Steven entering the Big Donut, and Lars avoiding him or Sadie
"I paid my money to the welfare line, I see you standing in it every time" = Steven asking for "the bits"
"The color of your skin don't matter to me, As long as we can live in harmony" = Steven & connie fusing into Stevonnie, Ruby and Sapphire fusing into Garnet
"I'd kind of like to be the president, so I can show you how your money's spent" = Nanefua running against Bill Dewey for Mayor
"Sometimes I don't speak right, But yet I know what I'm talking about" = Amethyst cracking her gem and speaking backwards (An Indirect Kiss)
"I know you're working for the CIA, they wouuldn't have you in the (Maf-i-ay)" = Peridot examining the equipment (Marble Madness), Peridot defying Yellow Diamond and telling her off (Message Received)
