Unfortunately some people share files that have been purchased online & are unable to be played by anybody else. So be aware of that.

Such files are DRM protected, meaning the person who purchased them, purchased them with "limited" permissions of use of them.

Best advice to people who do purchase online but wish to share their files -> Burn to a cd or cd-rw. Then extract them ... and share. BUT PLEASE say whether you have since converted them to any format such as mp3, m4a, etc. that you previously purchased them ... otherwise people will receive a lessor quality file for what they might think they are getting since online music is always lossy ... quality reduced due to converting to a smaller file for downloading online. You have the option to do this in the description or comments of the id3 tag of the song file.

ie: you can do this within LW by going to LW Library window, selecting shared file, press Describe button.
