The playlist consists of an Internet web path or URL, along with information about each track in the list (playtime duration). M3U8 files use UTF-8 character encoding as compared to M3U file types. M3U8 files can be opened using applications like VideoLAN VLC media player.

M3U8 files are stored to disc as text files and are a popular way to store playlists for music playback apps like Spotify, Apple Music and TIDAL.
