M3U (from MP3 URL) is a playlist file format.
Specification[]
An M3U file always starts with a line containing #EXTM3U
.
It then follows pairs of lines specifying information about the file and a path to the file. For example:
#EXTINF
- 372
,Sample song
C:\Users\J\Music\Sample song.mp3
Here, #EXTINF:
starts the line with the information about the song. The following number is the length of the song, in seconds. Following is a comma, then the title of the song. The next line specifies the path, either absolute or relative, to the song.
Comments may be specified by preceding a whole line with a number sign (#), but be careful as some extended formats may conflict with this syntax. Generally, placing comments is impractical with playlists.
The length of a song may also be specified as -1, where the path leads to a stream instead of a file.
