The title track of Miss May I's sixth album, this introduces the theme that runs through the LP. Lead vocalist Levi Benton said:
"Not only does this song open up our new record, it also sets the tone for the record. This album is all about changes throughout life, good and bad. It's about the past that lives within everyone; their 'Shadows Inside.' The lyrics talk about how great new things can give light to your past and put you in a better place."
Benton explained the creation of the song's music clip: "With this video for 'Shadows Inside' we not only wanted to recreate the cover of the record in real life, but we also wanted the performance to be abstract. We had black lights and used old lens effects from the '90s to achieve a very classic look and something totally different for us."
