Re: Winodws Media Player 11 Library Help?
Sometimes I get this problem, but it usually adds it to the library eventually. If you cannot find it, try right clicking on it in the now playing list, and click "Find in Library". If nothing happens, then it's yet to add it to the library. I am quite sure there's options in the player that allow you to make songs automatically get added to the library (which is done by default; but maybe you switched it off by mistake somehow).
