Nope. That list kept on their server. Whenever you, or anyone else for that matter, loads up your profile that info is retrieved from the Playlist server. The only thing that you'll need to update would be refreshing your profile page if you add any songs in another window or tab. It is a very nifty plug-in.
You can grab songs from other playlists to your playlist buy clicking that little add button on the side. The twisted arrows at the top is the randomizer for your list.
As you can probably ascertain by now, I don't fool with sites like MySpace or Facebook much.:blush5:
Anyway, that's good info to know on the playlist changings. This week, the ones I picked are a fine barometer of my moods, but then another manic episode will set in, and it'll be a totally different line-up.
