ClassicManager is an online library application that provides a free streaming service for classical music whose copyright has expired. The app is designed to build the world's largest classical music database and auto-filters public domain soundtracks in accordance with each country's copyright laws. ClassicManager is creating this service with the vision that its approach to the public through the history of past artists will lead to an interest in the artists who are currently active.

The app has a user-friendly interface with five menu options. Auto Music Search (AMS) allows users to create a playlist and listen to music with just one touch. The app provides mood, genre, artist, musical instrument, and customized auto-suggest features. Today's Albums feature allows users to see popular albums of the day, while My Favorites allows users to configure their own album groups by leaving a heart mark on their favorite albums, works, and artists. My Albums lets users make their own page by putting heart signs on the albums, works, and artists that they like. Lastly, Shared Albums lets users share the playlists they created in person and listen to playlists created by others.
