Well, it’s getting to cold outside to do outside sports, and for the exercise bike inside I need some really well-chosen tracks 😉
Since renaming the standard playlists to .pls worked fine, I have that available now, now I just need to setup my new soundbridge and some speakers in the attic 🙂
Feature might still be useful for others though, since the renaming is a bit tricky as you can see, and a few hundreds of useless playlists would make the connection quite slow (thousands of additional songs to be transmitted).
And remembering the discussion about hierarchical playlists (that feature since iTunes 6 or 7), the directory structure inside the playlist directory structure could just be directly mirrored.
