25 March 2015 :: Facebook opens up Messenger to third-party Apps. By giving people new ways to interact on Messenger, Facebook is hoping to keep their attention from wandering to rival services.
One of the new apps on Messenger is Ditty which sings personal messages to friends in the melody of famous songs.
Users type up to 70 characters, select a track such as “Counting Stars” or “Girls Just Want to Have Fun”
