Raja Rajamannar, Mastercard's CMO, shares his insights on marketing in the Inspired Execution podcast. He believes that a company's true differentiation comes from marketing, which combines data, technology, and creativity to deliver unique experiences. To achieve this, companies need a balanced team of marketers who excel in both creative thinking and quantitative skills. Sound plays an important role in marketing, with familiar jingles and melodies helping consumers associate brands with specific emotions. Raja shares how Mastercard created an album called Priceless to enhance its brand identity through music. He suggests that companies should consider "sonic branding" as part of their strategy due to the growing impact of audio marketing on consumers worldwide.
