Classical Archives, the largest classical music site in the world, offers several methods to play/explore classical music on its mobile application: 1) Library: (The Greats -or- by Composer, Performer or Title Search) which offers all the works we have by each composer, performer or matching title. Once you select a work, you can select what performance of that work you want to listen to. 2) Must Know: (By Composer -or- by Period & Genre) which is a list selected by our musicologists of the ~800 most important works of classical music you'll want to be familiar with. Selecting a work will always play the performance from the latest release (as opposed to The Library where you can select the performance.) 3) Playlists: (Featured and Mine) allows you to listen to featured playlists or to create, and listen to, your own. Up to 12 hour-long playlists are allowed. Subscriber account at Classical Archives is required. 4) Radio: Our radio will continuously stream either a series of single movements, or complete works (depending on your choice) that will be pulled from the selection of Period(s) and Genre(s) you select, from Early & Renaissance to Modern/Contemporary -- in the following genres, or combination of genres: from Orchestral, Solo/Chamber, Vocal, and/or Stage (incl. Operas). The radio will continuously refill the queue, until you stop the player. Depending on your Classical Archives' status (visitor, member or subscriber), you have complete access to all the complete tracks and works or you may only listen to clips of each track. There is no limit to the number of tracks or works you can play. This app offers a queuing player: you may enter a complete symphony plus a full opera if you wish. But there is one limit: you may add several works and tracks to the player only as long as the current queue doesn't already contain 20 or more tracks. Each time a track is played, it is removed from the queue and the count goes down.
