Lyrics: What happened to you? You're not the same Something in your head Made a violent change The song "Filler" by Benjamin Gibbard explores the transformation and changes someone goes through as a result of religious beliefs or a romantic obsession. The lyrics suggest that someone has undergone a significant shift in their mindset and personality. The opening lines question what has happened to the person, noting that they are no longer the same as before. The lyrics imply that something has occurred in their mind that triggered a drastic and possibly negative change. The chorus repeats the phrase "it's in your head," suggesting that these changes are happening within the person's thoughts and beliefs. The line "you call it religion, you're full of shit" implies that the person's newfound religious beliefs are seen as insincere or misguided. The lyrics further explore the impact of a romantic relationship on the person's life. The line "Was she really worth it? She cost you your life" suggests that their intense attachment to a particular person has had detrimental effects on their well-being. The chorus repeats again, indicating that these changes are all happening within the person's mind and perception. The line "if you call it romance, you're full of shit" suggests that the person's romantic notions are seen as false or unrealistic. The lyrics go on to describe the person's obsession with religion, symbolized by the line "You picked up a Bible, and now you're gone." This suggests that they have become deeply committed to their religious beliefs, but the narrator views it as a negative transformation. Throughout the song, Gibbard conveys a sense of frustration and disbelief towards the person's transformation. The repeated phrase "you're full of shit" suggests that the narrator believes the person's changes are insincere or misguided. Overall, "Filler" by Benjamin Gibbard delves into the themes of personal transformation, the influence of love and religion, and the questioning of one's authenticity in relation to these changes.
