Germany-based supermarket chain Aldi has become a significant grocery brand in the U.S. The chain's focus has been on low prices rather than luxury or convenience, a strategy that has gained it a loyal customer base.

Playing music is a common retail psychological tactic to subtly manipulate shoppers' behaviors, but Aldi doesn't use this approach, because keeping prices low is its primary way of attracting customers and generating business. By not playing music, the store doesn’t have to pay licensing fees to a third-party music service.

In addition, the lack of background music adds to Aldi's efficiency, as each store has been set up to get customers in and out as quickly as possible. Music would only derail the company's plans since it encourages relaxed wandering and browsing.
