Simply drag & drop songs or even folders of songs onto the Public Shared icon at the left side of LW's interface. That's if using LW 5.2 or later. This will immediately make the files available for others to upload. If you choose the Library icon instead, the files will not be shared, you'd need to select which ones to share & right-click them & choose share. More about how to share here
