Looking Back and Letting Go: Unpacking the Meaning Behind 5 Seconds of Summer’s “High”

When 5 Seconds of Summer (5SOS) released their fourth studio album, CALM, fans were treated to a mature, introspective evolution of the band’s signature pop-rock sound. Serving as the emotional final track on the standard edition, “High” acts as a bittersweet conclusion that captures the messy, vulnerable reality of a relationship that has run its course.

Far from a bitter breakup anthem, the song is a delicate reflection on nostalgia, unmet expectations, and the complex desire to be remembered fondly by someone you have lost.

1. The Core Dilemma: Hoping for a Favorable Legacy

At its emotional center, “High” grapples with a very human insecurity: How do you cross someone’s mind after you’re gone?

The song centers on the lingering hope that a former partner still thinks of the narrator in a positive light, even as distance and outside noise creep in. The lyrics touch on the friction of dealing with external opinions—specifically, knowing that a partner’s friends might not approve of the narrator or may have actively worked to pull them apart. It highlights that deeply uncomfortable post-breakup phase where you wonder if your narrative has been completely rewritten by the people surrounding your ex.

2. Idealized Versions vs. Harsh Realities

One of the most poignant themes in the track is the struggle against unrealistic expectations. Relationships often suffer when one person falls in love with an idealized version of their partner rather than who they actually are.

“High” captures this tension by highlighting how difficult it is to live up to the image someone else painted of you in their mind. When you walk on eggshells because every step feels heavy with hesitation, the relationship becomes exhausting. The narrator notes the pain of trying to evolve—calling to share that they are actively changing—only to realize the other person lacks the respect or willingness to witness that growth.

3. Nostalgia and the Weight of Golden Memories

The song’s title and key refrains draw heavily on nostalgia, looking back at the lighter, happier mornings shared with a partner. These memories act as a double-edged sword:

• The Comfort: They represent a time of genuine connection, freedom, and intimacy.
• The Trap: Clinging too tightly to those past moments makes it harder to accept that the present reality has changed.

The track honors the beauty of those memories without romanticizing a dynamic that ultimately stopped working.

4. The Shift Toward Self-Compassion

Perhaps the most crucial takeaway of “High” lies in its internal pivot. Beneath the heartbreak over an ex’s perception is a deeper realization about self-sabotage and personal accountability.

Repeatedly, the lyrics emphasize a hard-earned truth: the narrator needs to stop letting themselves down. While the song begins as an outward-facing query about how an ex views them, it ends up being an inward-facing healing process. It acknowledges that moving on isn’t just about losing someone else—it’s about forgiving yourself, recognizing your own worth, and realizing your heart is resilient enough to heal from more than just a fleeting night of pain.

Final Thoughts

“High” resonates so deeply with listeners because it refuses to wrap heartbreak up in a neat, simple bow. It captures the grey area of a breakup—where sadness, fondness, frustration, and personal growth all exist at the same time. By blending an uplifting, driving rhythm with vulnerable lyricism, 5SOS turned a goodbye into a cathartic reminder that while memories endure, learning to stop letting yourself down is the ultimate step toward moving forward.
