export playlist (mpl, html, txt, asx, m3u, wpl). selecting txt will allow All Fields type of export, and it's a CSV file so it opens really nice in Excel. this is the only export list option i ever use. you can either select the files then export selection, or export all at once
you can export your library as an XML (file>library>export to XML)
you can select all files and Print List (to a .pdf or something like that)
