Topic: SHAZAM THAT BRAND! Brands That Move With Music
What people listen to, and choose to save, share, or Shazam, has become one of the clearest signals of identity, values, and cultural belonging. In a world saturated with content, music remains one of the few creative forces people actively invite into their lives. This talk explores how brands can tap into that intimacy by treating music not as an accessory, but as a creative starting point. When brands listen closely to audiences, to artists, to culture, they can collaborate on original, playlist-worthy songs that feel meaningful rather than manufactured. Drawing on real campaigns and artist collaborations, the session reframes branded music as a form of cultural participation. It argues that creativity has its greatest power when it gives people something they genuinely want to keep, long after the campaign ends.
