You can actually do this without using regexps or the markup function.
Just set the following variables in local/config.php:

   $LinkFunctions['play:'] = 'LinkIMap';
   $IMap['play:'] = 'player.php?path=$1';
   $IMapLinkFmt['play:'] = 
     "<a target='player' href='\$LinkUrl'><img src='track.png' /></a>";

The nice thing about doing it this way (as opposed to using Markup() )
is that PmWiki automatically knows which characters are valid in urls, 
will url-encode characters as needed, and automatically handles markup like
[[play:some path with spaces]] and [[(play:)mysong.mp3]].
