7MC playlists

I've been using iTunes for ages now and find it easier to create playlists using that than creating playlists in 7MC.

In iTunes, just export your playlist as m3u and then import into WMP and they'll appear in 7MC

Once WMP knows about the playlist, it reads it in from the disk location, so it's easy to make additions to your playlist in iTunes, then just export out over the top of the original file.
