PLS (file format)

PLS is a computer file format that stores multimedia playlists, originally used by SHOUTcast and Icecast for streaming media over the Internet. PLS is a more expressive playlist format than basic M3U, as it can store (cache) information on the song title and length (this is supported in extended M3U only). With PLS version 2, playlists also include a PLS version declaration.
iTunes, VLC media player, Totem, RealPlayer, Winamp, Yahoo! Music Jukebox, MediaMonkey, Windows Media Player, AIMP, XBMC, XMPlay, Rhythmbox, foobar2000, and more than 30 others are able to interpret (open) PLS files. Media Player Classic with the K-Lite codec installed does work with PLS format but still requires the appropriate MIME or file extension associations.
