Swift, saying that she was speaking up for artists afraid of upsetting Apple, had called the company's behavior "shocking" over its earlier plan not to pay for streams during customers' initial three-month free trial.

Eddy Cue, Apple's senior vice president of Internet software and services, said late Sunday that the company had shifted course and would compensate for streams in all stages.

Apple Music "will pay artist(s) for streaming, even during (customers') free trial period," he wrote on Twitter. Mimicking Swift's earlier protest, Cue wrote, "We love you (Taylor) and indie artists. Love, Apple."

Cue separately told industry journal Billboard that he telephoned Swift, who is in Amsterdam on her tour, after receiving approval from Apple CEO Tim Cook. He insisted that Apple never intended to avoid compensation and had heard plenty of concern from others besides Swift, although he was moved to action after she went public.
