You can organize and listen to music stored on the projector’s internal memory or 
SD card. 

Music utilizes the same file and folder structure as many media player applications 
for your computer. In most cases, you should be able to copy your song libraries 
and playlist onto the projector’s memory or SD card. 

Music searches the projector’s internal memory and SD card for supported audio 
files and playlists. The supported audio formats are: MP3, M4A, AMR, MIDI, 
and OGG Vorbis. It does not support audio files that contain DRM (Digital Rights 
Management).  

Once Music finds audio files, it looks for:

t

The folder containing the songs and uses the folder's label as the album 
name.

t

A folder containing the album folder and uses the folder's label as the artist 
name.

t

Album art. The album art work must be in the same folder as the music and 
be labeled “albumart.jpg”.  

For best performance, place you music library into one folder such as a folder 
labeled “Music” or “My Music”.  For information about transferring files to the 
projector, see Transferring Files to the Projector.

After you have copied your music to the projector, you can open Music and see your 
library of music files. You can view your music files sorted either by Artist, Albums, 
Songs, or in Playlist. The main screen for Music is called the Library.
