S3·E16 Hit the Road, Chad

Samantha thinks her boyfriend Chad is the cat's meow when he writes a song just for her. Word gets around, and the tune is heard by legend Ray Charles whom Angela cooerses into recording it for her ad agency. When rat Chad starts seeing another girl, Samantha is so infuriated she demands the recording not take place. It takes a stellar performance of the song by Ray to make Samantha see that her friendship with Angela is more important than getting back at Chad.
