The document discusses the use of lighting in music videos for three songs: Lady Gaga's "Bad Romance", Rihanna's "This Is What You Came For", and Kendrick Lamar's "Swimming Pools". For "Bad Romance", lighting is used to enhance Lady Gaga's creature-like character and show her darker side. In "This Is What You Came For", lighting goes dark during choruses and is used with strobes to intensify drops in the song. For "Swimming Pools", changing lighting from black to white and using darker tones represents the dark themes of alcoholism and drinking portrayed in the lyrics.
