Part of it already exists in 2.0, in the std.file.dirEntries and 
.DirIterator code.  It needs to take a delegate or other filter 
mechanism to gain the rest of the power.  But as is it'd simply the 
example of a bit of it (untested).

     string[] files;
     foreach (DirEntry de; dirEntries(fromdir, SpanMode.depth))
     {
         // Collect only files with mp3 and wma extensions
         auto ext = getExt(de.name);
         if (fnmatch(ext, "mp3") || fnmatch(ext, "wma"))
             files ~= de.name;
     }
