Exporting iTunes and Windows Media Player playlists to .m3u-format.

Windows Media Player and iTunes do not use standard formats, such as .m3u, to store the playlists that users create. This can be a problem for users migrating to other players such as MediaMonkey, WinAmp etc. Luckily, all is not lost; Windows Media Player has functionality for exporting playlists built in, and there are tools that will convert iTunes playlists to .m3u format for you.
 
Windows Media Player

1. Click Library
2. In the Contents pane (the left pane), expand the My Playlists category, then click a playlist to make it play.
3. On the File menu, click Save Now Playing List As (Save Playlist As in Windows Media Player 9 Series), click Save as type, and then click M3U Playlist(*.m3u).
4. In the File name box, type a file name for the M3U playlist, and then click Save.

 
iTunes
As mentioned, this is not functionality that is provided by default. To convert the playlists, download and run either of the following tools:

• iTunes Export
• Export Playlist to .m3u
