Rocket Songs connects top quality unreleased songs from the best music publishers, songwriters, and producers, to musical artists from around the globe. However, not all of these recordings have their stems, which can be an crucial ingredient for an artist who loves the track but wants to make a change--change up the drums, for example, or to remove an a capella. Rocket Songs uses AudioShake to make stems available for all its catalog, giving its customers maximum flexibility in how they interact with the recordings.
