Song: "Her Hollow Ways" by Danger Mouse & Daniele Luppi
Why's it part of the "Rome, Italian Style" playlist?: This lush instrumental from Danger Mouse and Daniele Luppi's Rome album sounds so much like a theme from some late '60s or early '70s Italian drama about either star-crossed lovers or a sexually repressed housewife who masturbates in the bathtub a lot that you can practically see opening credits in white like "Musica composta, orchestrata e diretta da Danger Mouse & Daniele Luppi" as you hear it.
Some YouTuber took "Her Hollow Ways" and added it to a slideshow of vintage photos of elegant '50s and '60s ladies from Life magazine's Web archives for some reason. It kind of works.
