Can I add the currently playing song to my iPod On-The-Go-List?
Well, the concept is basically that you add a song to the on-the-go list rather than listening to it right that instant. So the playlist functions work on the song browsing list and not on the currently playing track. It’s kind of the whole point and raison d’etre of the on-the-go playlist–it helps you pick what to listen to *next*. If you bring it up on Apple’s Discussion Forums maybe there’ll be a groundswell of user support and Apple will add something like this in a future firmware update. You could, as you suggested, make a smart playlist in iTunes that resides on your iPod that includes all, say, songs rated with one star. Then you could change a song’s rating to one star on the fly and build a playlist that way.
