The iPod doesn't have a "Now Playing" playlist, so you can't do anything with the music you're listening to.

The best/easiest thing to do if you have n iOS-based iPod or iPhone, is to simply start using a different music player app, like AMP. The one big unfortunate thing with it at the moment is no support for landscape mode.

There are other programs that while not great music players, are good for using in landscape mode while in the care, with extensive gesture controls so you don't have to look at the screen to manipulate your music.
