What is a music playlist?

Playlister originally used only video or still graphic components for playlists, but since then has upgraded to offer the ability to play MP3 audio files as well, so it is now possible to compile a music playlist of songs only, or a combination of songs and videos, that is sharable to families at home or to other locations, such as additional campuses set up with the same Playlister account. Graphics may be added to songs in the playlist as well, so it would be possible to play a certain song while also showing a specific slide. This is a great way to compile a music playlist of songs to play while people are entering the room for a service or event.
