If you want WMP to play songs that you download from Limewire.
You need to tell WMP to monitor the DL folder. On my PC this folder is called shared and is in the My documents folder on my desktop. the DL folder is where LW stores all my downloaded movies and songs and anything else I DL form Limewire.

1. Open WMP
2. Click on File then
3. Add to libary (or you can just press F3 at the top of your keyboard)
A small window opens with add to libary in the header.
4. just under the blue text which reads "select folders to monitor"
select my folders and those of other which I can access
5. Click on Add
6. navigate to the folder where your downloads are stored. ( to get to my shared folder I used this path My Computor / Data (D / Documents and Setings / my user logon name for me this is called Me on your PC it will be diff)
Shared /
7. click OK

Now look at the list of monitored folders you should see the download folder and manually added after it.
Click OK

This should solve the problem.

If no joy let us know........
