"Cardigan" is the second track on Taylor Swift's eighth studio album, Folklore. It's a melancholy soft rock ballad that features minimal orchestration and examines the topic of young love. In the music video, directed by Taylor Swift herself, her piano acts as portal to different settings.

"All Too Well: The Short Film" is based on an extended version of the song by American singer-songwriter Taylor Swift, and was directed by Swift herself. It follows the relationship of a young couple through its ups and downs.

The song “Anti-Hero” from Taylor Swift’s album Midnights is inspired by her own fears and issues with self-esteem, as she allows herself an introspective look into her darkest thoughts. Taylor has said that the track is “one of my favorite songs I’ve ever written.”

On the first song from her album The Tortured Poets Department, Taylor bares her soul about a betrayal and relationship breakup. The song and video feature American rapper, singer-songwriter and producer Post Malone.
