m3u extended playlist comments useful?

[adrian]

I have been trying to figure out a system for constructing playlists, and I realized that the m3u format is simpler than I thought: all I actually need is just a list of files and the .m3u extension.

So I'm wondering whether the extended playlist comments, the #EXTINF data, serve any purpose. Does MinimServer benefit from these? (Do other players?)

In my collection I have flac files (that MinimServer serves) and I have a second copy of my music in mp3 for putting on devices where space is a consideration. I understand that mp3 files aren't the same length as the original (there is some sort of padding) so that means I if the #EXTINF information is present, I couldn't just convert a flac based m3u file to an mp3 based one with a script that changed occurrences of flac->mp3. Am I right about that?
