Abstract: A method for improving a digital media player experience is disclosed. In one embodiment, a digital media player storing a media transfer protocol database determines that digital media content stored on a removable memory device connected with the digital media player changed since the media transfer protocol database was last updated. The digital media player then refreshes the media transfer protocol database with metadata associated with the digital media content stored in the removable memory device. In another embodiment, a digital media player stores digital media content in the removable memory device, stores auxiliary information associated with the digital media content in a memory of the digital media player, and stores the auxiliary information in the removable memory device. In this way, the auxiliary information is portable with the removable memory device and accessible by a second digital player when the removable memory device is placed in communication with the second digital player.
