I listen to many podcasts, and they post their episode playlists in several different styles. I've created this tool with JavaScript regular expressions to automatically format all kinds of playlists to upload them with Last.fm tracklist Scrobbler.
You can use it to trim blank spaces and lines, remove additional track info between parentheses or brackets, and reverse the order of the items from "Song - Artist" to "Artist - Song". For more listing options, see Alphabetizer.
