m3u skips first song, rest are fine (default music plugin)

[bungle]

I have some m3u playlists created by CDEx when ripping my CDs. These are non-EXT versions. It's the newest CDEx but it only puts the filenames in there, no #EXT lines. Anyway, selecting the playlist always starts on song 2. If I put a comment line as the first line in the m3u file, then the first song plays. It doesn't even have to be #EXTM3U, #foo works as well. What is expected on the first line? From research on the format it doesn't seem like anything is required.

Standard music plugin, GB-PVR 95.16

All the .m3u files I'd seen had #EXTM3U as the first line, so the first line is discarded. I've just changed this now for the next build.

Cool. Seems only extended m3u's have that (info from Google). There are also provisions for other lines - all but the filename ones start with # (comments essentially).

I do skip other lines that start with #, but always assumed one header line.
