Análisis de las letras de Taylor Swift: folklore

folklore

Usando las instrucciones de Ariane Aumaitre en su blog hice un pequeño análisis de las letras de las canciones del album folklore de Taylor Swift. Lamentablemente, no pude usar el paquete genius, así que descargué una por una las letras del album usando el paquete geniusr. Para usar este último paquete, es necesario crear una cuenta en genius.
