Plugin to fix playlists

  Hey guys , I've been meaning to write about this idea for some time 
now and I finally got to it . I want to make (or help make ) a plugin to 
fix paths of songs in playlists .
  The problem - when I export playlists from say iTunes , they have the 
Windows paths in , so they are practically broken . Not to mention that 
any time you organize your music (through rearranging files) playlists 
may get broken .

  The plugin would rely on the consistent filenames . Simple cycle :

For (every song in the playlist) {

//get filename from the path recorded in the playlist

//find the song in the library by filename

//get the path ,stored in the library

//record it back in the playlist

}

  It would be great to have this integrated in RB itself (to fix upon 
importing a playlist) , but I don't know how liberal the development is 
towards such functions :)

Best Regards ,
