Here's how to create a playlist in Windows Media Player.
Start by opening the Start menu and selecting Windows Media Player from the list of programs.
Select Create playlist from the top left-hand corner of the Windows Media Player window. A new playlist will appear in the far left-hand side of the window. Begin typing to give the playlist a name.
Now select Music to browse tracks in your library and then drag and drop them onto your playlist.
To begin listening to your playlist, simply click on the playlist and press the play button at the bottom of the Windows Media Player window.
