That's inside out. You want the same audio/video element (with the  
same controller connected to it) to play a list of media items in  
sequence so it's hooked up to the same controller, etc. I don't think  
the <ul> use case makes sense. <playlist> could just be allowed to  
contain <li> elements directly, the problem is that it would make the  
<li> content model context-sensitive which is a bit annoying.
