Playlist has taken over iTunes

This is odd. Yesterday, I updated a Beatles playlist. At least, I tried to. Unfortunately, there doesn't seem to be anyway to be finished. There is no "Done" button. Nor "delete". Whenever I go to a different artist, album, playlist, whatnot, I only have the option to add everything to this Beatles playlist. So, none of my music is available to listen to.

I tried syncing it with my computer and even deleted the Playlist in question. So, it's not currently on my iPhone but it still is ONLY giving me the option of adding music to it. What's it's adding to, I have no idea.

So, short of "Restore", any ideas on what I might try?

Thanks.

Brian
