Taylor Swift has ''happily'' agreed to stream her album on Apple Music.

The 25-year-old singer is delighted the technology giant agreed to reverse their decision not to pay artists for songs streamed during users' free trial periods after she spoke out earlier this week, so will now allow her latest record '1989' to be made available via the streaming service.

She tweeted: ''After the events of this week, I've decided to put 1989 on Apple Music...and happily so...

''In case you're wondering if this is some exclusive deal like you've seen Apple do with other artists, it's not...

''This is simply the first time it's felt right in my gut to stream my album. Thank you, Apple, for your change of heart.(sic)''

The 'Blank Space' hitmaker - who had her music removed from rival service Spotify last year - previously hit out at the company's ''shocking'' decision not to pay artists.

She wrote on her Tumblr page: ''I'm sure you are aware that Apple Music will be offering a free 3 month trial to anyone who signs up for the service.

''I'm not sure you know that Apple Music will not be paying writers, producers, or artists for those three months.

''I find it to be shocking, disappointing, and completely unlike this historically progressive and generous company.''

Although Taylor acknowledged the move will not make a huge difference to her own financial wellbeing, she insisted her actions were not those of ''a spoiled, petulant child''.

The 'Bad Blood' hitmaker concluded her letter: ''It's not too late to change this policy. We don't ask you for free iPhones. Please don't ask us to provide you with our music for no compensation.''

Following the publication of Taylor's letter, Eddy Cue, the Senior Vice-President of Internet Software and Services at Apple, vowed the company would change its policy.

He tweeted: ''#AppleMusic will pay artist for streaming, even during customer's free trial period.

''We hear you @taylorswift13 and indie artists. Love, Apple.''
