Windows Media Player/General Music Question

[deandiggity]

I can't for the life of me figure this out on my phone. I put music on and it is playable, but it won't show up in my library. Which is a problem when I want to play all my songs on shuffle. This wouldn't be a problem if I could figure out how to put together a playlist.

Could anyone who knows about this just give me some general idea of how to do it.

Thanks.
