Apple Music today announced a new initiative called “Digital Masters”, which aims to combine all its songs “Mastered for iTunes” into a single streaming catalog.

Apple has been slowly introducing Mastered songs for iTunes in Apple Music for some time. The company said that 75 percent of the 100 best songs in the United States are Apple Digital Masters and that 71 percent of the 100 best global songs are already part of the new program.

Apple started the Mastered program for iTunes in 2012, allowing engineers to optimize the music for the digital download format by encoding them at high resolution. This placed the iTunes songs as close as possible to the original recordings, and was specially designed as ” Burned to iTunes “.

In Apple Music, Apple does not show whether a song is in its Digital Masters program or not. However, for people who care about audio quality, it is a good sign that the company has formally recognized a plan for adding more high quality audio tracks to Apple Music.
