SonicStage, a fully-featured program that will help you manage all your audio files with ease, is called a "full-featured" tool.
You can create your own music collection and play them with the built-in music player. It supports both well-known formats as well as less-known ones.
You can choose between a standard interface and a simplified one that only has the most common controls. This is a great option if you do not want an interface with too many buttons.
SonicStage is easy to learn. You can use the music library to classify and organize your music. You can also import audio CDs and other removable drives.
SonicStage offers the ability to burn music collections and transfer music to portable devices.
