Permissions to use a protected Windows Media-based file in a particular way. For example, a content provider, such as an online music store, can grant you the right to play a song on your computer (a play right), to burn the song to an audio CD (a burn right), or to sync the song to a portable device (a sync right). The content provider dictates the terms of the rights (for example, which rights it grants to you and for how long) and Windows Media Digital Rights Management(DRM) enforces those rights.
