I download songs and I can play them from where it says 100% downloaded but then they don't appear in the library. Can anyone help, it's really annoying

You have to add your saving directory as a shared folder in the options.

I'm having the same problem and my saved directory is set up... the only folder that is in my library is incomplete, but when i go through the program files there is a shared folder.

Then go to the library window and add the "Shared" folder with File->Add Folder To Share.
