The fusion of pop and funk elements in "Ghost" cut through an air of melancholy. It combines pop sensibilities, funk guitar riffs and basslines and ghostly, haunting bells, synths and eerie organs drenched in heavy reverb. Rennison expresses complex emotions and inner turmoil through indie-pop piano balladry as he digs deep to give us this soul-stirring piece of art.
Rennison sings about a transformation in a relationship and the feeling of being distant and unseen as lovers begin to fade away. The emotional impact of this shift captures the essence of vulnerability and detachment. He's aching to find a way out of the emotional strife. "Just two strangers on their own," Rennison sings, "stuck up in the shadows / hear my cage rattle / cause I finally understand / that I'm a long way from home / and I can feel it in my soul / guess I always was a ghost." Expressing a sense of detachment and being far from home, he channels his frustration and anger in the song's double hook at the end.
"Ghost" stands as an emotional monument, born from Rennison's personal journey of feeling detached and invisible. It's a glimpse into the raw vulnerability and anger that reside within us all, capturing the complexities of human emotions and the power of music to express what words alone cannot convey.
