If you don’t own the sound, you don’t own the memory.

There is a reason you can hear a few notes and instantly know the brand behind them (aka Toyota’s “da da da da”). Long before we read a logo or see a colour palette, our brains respond to sound. Music is not decoration in advertising, it’s memory architecture.

In a world where attention is fragmented and visual identity is increasingly crowded; sound has become one of the most powerful shortcuts to brand recall and emotional connection.

Why music works so powerfully in the brain

Music is one of the few creative assets that engages emotion, memory and anticipation simultaneously. It bypasses rational processing and lands directly in the limbic system, where emotional memory is formed.

This is why a simple melody can trigger recognition faster than a visual cue (strum Woolworths ‘Fresh Food People’ E-A-A-A-B-G). It’s also why music tends to increase both attention and recall, particularly in low involvement environments such as social feeds or short form video.

In essence, the brain doesn’t treat sound as background, but rather as meaning. So why do brands producing videos, reels and TikToks mostly default to platform supplied music libraries? On the surface, this appears efficient. In reality, it’s a strategic compromise.

When brands use trending or platform music, they are borrowing an existing cultural signal. Emotional equity belongs to the track, the artist, or the platform. The brand becomes visually present but sonically invisible.

This creates a structural memory problem.

If every piece of content uses a different audio identity, the brain has no stable cue to anchor brand recall. Activity increases, but encoding doesn’t. Reach is achieved, but memory isn’t built.

This is one of the most overlooked inefficiencies in social content strategies. Brands are producing high volumes of posts without building any consistent sound asset to unify it.

A sonic identity or MOGO (Musical Logo) used consistently across sound-based environments solves this. It acts as a recurring memory trigger. Even when creative execution changes, the sound signals continuity. That continuity is what builds recognition over time. Circling back to Woolworths, it has higher brand recognition and value than Coles (Brand Finance valued WW at $19.1B and Coles at $8.8B in Jan 2026).

Research from System1 Group constantly shows that emotional consistency is a primary driver of long-term brand memory formation. In social channels, sound is the fastest mechanism for achieving that consistency, yet it remains one of the least controlled brand variables.

The result is a growing imbalance. Brands are optimising for content output, not memory formation.

Jon Evans, host of the Uncensored CMO podcast, speaking at the 2026 Cairns Crocodiles, was asked what he would have done differently when managing global brands. Without hesitation, he replied, ‘I wish I’d known the power of music. I would have invested far more heavily in it over other elements’. It is a striking reflection, particularly from someone who has operated at the highest level of global marketing.

The same thinking is evident in Netflix. They made a decisive investment in sonic identity, resulting in its now iconic “ta-dum” to reflect a theatre viewing experience. It is distinctive, and immediately recognisable from the first moment the platform is activated. More importantly, it signals brand presence before any visual narrative begins, embedding itself as part of the experience rather than sitting alongside it.

Drumroll….Sound is not an add-on to identity. It is identity.
