Convert an xpsf file to m3u

To convert an xspf file to mp3, it's really simple!
First, you need to open it with VLC
Then, you click on "playlist", the 7th icon from the left at the bottom (the icon with small horizontal bars)
A window opens with your playlist and the xspf title you want to convert
Right-click on the current title
Then click on save
Another window opens
Choose "audio mp3" as the output format
Select the destination file and then click start
You'll see the small blue bar in VLC running for a few seconds
When it reaches the end, the result is done!
Retrieve your file, now in mp3, and listen to it or work on it with Audacity for example (since Audacity doesn't natively open xspf files)
There you go...
