"Can't play what it can't find"
It's stupid simple
Stupid... it's that simple
There are at least fifteen songs on my computer, (yes, they're in my "Music Library" with all my other songs) that WMP can't see on it's own. If I double-click the song from Windoes Explorer, WMP plays it just fine. But if I open WMP and try to find the song, the player comes back with nothing.
You can't add a song to a playlist if the program can't see it on it's own.
