E.g. in the m3u file below, the running times are listed as 419, 260 and 255.

 #EXTM3U
 #EXTINF:419,Alice In Chains - Rotten Apple
 Alice In Chains_Jar Of Flies_01_Rotten Apple.mp3
 #EXTINF:260,Alice In Chains - Nutshell
 Alice In Chains_Jar Of Flies_02_Nutshell.mp3
 #EXTINF:255,Alice In Chains - I Stay Away

  • Is it possible to write an m3u file without these properties?

    • Or just include some kind of default?

      • Are there repercussions?

  • Since you seem to have copied that example straight from [the Wikipedia page on the M3U playlist format](http://en.wikipedia.org/wiki/M3U), you could’ve _read_ there yourself also that only some kind of path or URL is required, and everything else are optional extras … – CBroe Sep 06 '13 at 13:27

There is no standard for m3u. The time is optional. You can enter just "1" for time if you want. Furthermore, the entire line is optional:

#EXTINF:419,Alice In Chains - Rotten Apple
 Alice In Chains_Jar Of Flies_01_Rotten Apple.mp3

Could be replaced with: 

 Alice In Chains_Jar Of Flies_01_Rotten Apple.mp3

The #EXTINF: tag is for the extended format. As a matter of fact it is not even understood by some players and will cause the entire playlist to appear as empty.

I think this depends a lot on what is going to read the playlist.

The most basic m3u file just contains the list of files (or URLs) without any of the '#' lines. In this format the player will have to read the files if it wants to know their duration. This could be slow especially for URLs.
