“Skylines and Turnstiles” is My Chemical Romance’s first studio track. It appears on their debut album, I Brought You My Bullets, You Brought Me Your Love. Frontman Gerard Way wrote the song after witnessing the 9/11 terrorist attack on the World Trade Center firsthand.

A turnstile is a pedestrian gate used to let one person through at a time. Turnstiles can be found throughout New York City, the place of the attack, most commonly found in subways under the city. Having turnstiles in the skylines is a poetic way of describing individual lives lost in the air.
