Profits from downloads will be donated to charity.
Unsatisfied with its finger in the gaming and film pies, Rovio has moved into music. Don't fret, the move isn't permanent.
Seemingly feeling festive, the publisher has launched an Angry Birds Christmas song entitled 'Fly Me Home Tonight'.
Rovio, said: "We’re donating the profits from downloads of the song to Save the Children and their efforts to establish clubs for schoolchildren in developing countries.
"These clubs encourage kids to play and have fun while also learning key life skills that will improve the quality of life for them and their families. It’s a great cause, and we’re proud to support it."
The charity support follows Disney's decision to donate £1 for each download of its new 69p Fairies game.
