I've seen the post related to UNC paths in playlists and the need to edit them and adjust paths to relative paths.
I generally create my m3u playlists in Windows Media Player on my network clients and it would be great to not have to search and replace text to make them usable in Subsonic -- making them unusable on my clients.
I'm a new (registered!) user of Subsonic and am still amazed at its functionality. I hope we continue to see it evolve!
Best,
