Since news of his death, a single question had been haunting me: What was the last song he’d ever listened to? Now I’d finally know. The song that played was a familiar one. It was called “Always in My Head.” A Coldplay song. The band that had inspired him to play piano. A band we’d both listened to on repeat when we were kids, sitting in the back seat of our parents’ car. The same band that had ushered him away from me.
