M3U Playlist Ignored in WMP — One Item Fix

Why This Happens — The One-Item Playlist Problem

You open an M3U playlist in Windows Media Player (WMP) and instead of seeing your list of songs, you get nothing. Or maybe just one track shows up. The error code 0X000D1108 means WMP saw your playlist, but it collapsed it into a single media item and ignored the rest.

I had a client last month who spent two hours trying to get his morning commute playlist to work. He'd copied an M3U file from his old PC to a new Windows 10 machine, and WMP just wouldn't play ball. Turned out the playlist file had one extra blank line that messed everything up.

Here's the deal: M3U files are simple text files that list file paths or URLs, one per line. WMP has a quirk where if the file contains only one valid media item (or it thinks it does), it treats the whole playlist as a single media object. The rest gets dropped. This usually happens because of how the file is saved or formatted.

Let's fix it.

Cause #1: The M3U File Has Only One Valid Entry

The Fix: Check and Rebuild the Playlist

First, open the M3U file in Notepad. Not Word or WordPad — plain old Notepad. Right-click the file, choose Open with, and pick Notepad. You'll see something like this:

#EXTM3U
#EXTINF:123,Song Title - Artist
C:\Music\song.mp3

If that's all there is, WMP will collapse it. The fix is to add more songs. But maybe you already have more songs in the file and they're not showing up. That's a different problem — keep reading.

If the file genuinely only has one song, you need to add more media. Either add more lines with different files, or merge it with another playlist. Simple as that. If you only want one song, don't use a playlist — just play the file directly.

I tell clients: playlists are for multiple items. If you only have one song, skip the M3U and double-click the MP3. Saves you this headache.

Cause #2: The File Paths in the M3U Are Broken

The Fix: Use Absolute Paths or Fix Relative Ones

This is the most common cause I see in the wild. Your M3U file contains paths like:

..\Music\song.mp3

Or even just filenames with no path at all:

song.mp3

WMP has to guess where those files are. If it can't find most of them, it might treat the whole playlist as having one valid entry — and collapse it to that one. I saw this with a small business that shared playlists across network drives. The paths were relative, worked on one PC, failed on another.

Fix it by using full absolute paths. Open the M3U in Notepad and change each line to the full path:

C:\Users\YourName\Music\song.mp3

Or if you're using network paths, use UNC paths like this:

\\Server\Share\Music\song.mp3

No quotes, no spaces at the end of lines. Save the file with the same .m3u extension. Then try opening it in WMP again.

Pro tip: If you have dozens of songs, don't type them out. Use a tool like MP3Tag or Playlist Creator to regenerate the M3U with proper paths. Or use PowerShell to batch-replace paths.

Cause #3: The M3U File Has Hidden Characters or Wrong Encoding

The Fix: Save as ANSI or UTF-8 Without BOM

This one's sneaky. Windows Notepad sometimes saves files with a Byte Order Mark (BOM) at the start, especially if you use UTF-8 encoding. WMP chokes on that BOM and misreads the file. It sees the first line as garbage, then might only pick up one song after that.

I had a client who exported an M3U from iTunes on a Mac, then opened it on Windows. iTunes added some weird invisible characters. The playlist looked fine in Notepad, but WMP collapsed it to one track every time.

To fix this:

1. Open the M3U file in Notepad.
2. Click File -> Save As.
3. At the bottom, in the Encoding dropdown, pick ANSI. If ANSI isn't available, pick UTF-8 without BOM (this might require a better editor like Notepad++).
4. Save it with a new name, like fixed-playlist.m3u.

If you don't have Notepad++, you can also use the command line. Open PowerShell and run:

Get-Content original.m3u | Set-Content fixed.m3u -Encoding Ascii

This strips any BOM and forces plain ASCII encoding. Then try the fixed file in WMP.

One more thing: if the file was created on a Mac or Linux, those systems use different line endings. Windows uses CRLF (carriage return + line feed), while Unix uses just LF. WMP sometimes misreads the file if line endings are off. You can fix that in Notepad++ too: Edit -> EOL Conversion -> Windows Format.

Quick-Reference Summary Table

That's it. Nine times out of ten it's one of these three things. Start with checking the paths, then encoding, then add more songs if you really need to. You'll be back to listening in no time.
