Surely!  Two notes to start off... first, the request path is a stack, so
'path[0]' is the *final* path element.  You want to test 'path[-1]'.
Second, from my own experience I no longer recommend trying to subtly pick
out management interactions from regular interactions.  Now I just make my
use of the management interface explicit by prefixing everything with 'Z'.
Such a session starts with 'http://mysite.com/Z/manage'.

Now, If you really meant what you said about 'folders that do not exist',
then you might want to try:

<dtml-let path="REQUEST.path">
<dtml-if path>
  <dtml-if expr="path[-1]=='Z'">
    <dtml-call expr="path.pop()">
    <dtml-call expr="REQUEST.setURL(path='Z')">
    <dtml-return expr="'done'">
  </dtml-if>
  <dtml-if expr="path[-1] in objectIds()">
    <dtml-return expr="'done'">
  </dtml-if>
</dtml-if>
  <dtml-call expr="path.append('artists')">
  <dtml-call expr="REQUEST.set('SiteRootPATH', '/')">
</dtml-let>

If, on the other hand, you really do just want to list names to be left
alone, change "path[-1] in objectIds()" to "path[-1] in ['artists',
'players', ...]"
