The LA Times is reporting that Apple is expected to announce today a promotion deal that would give Pepsi buyers free songs from Apple’s iTunes Music Store. “Sources said the unveiling of the pact with PepsiCo Inc. was timed to coincide with today’s release of a Windows-compatible version of Apple’s iTunes… The sources said Pepsi was expected to craft a multimillion-dollar ad campaign around the music store, which charges 99 cents for each song… Consumers who purchase Pepsi beverages would find codes in the packaging that they could redeem online for free downloads from iTunes. Pepsi will pay Apple for each of the songs downloaded during the promotion, the sources said. They said Pepsi and Apple have discussed offering about 100 million free songs.”
