strange output with du

Can someone please explain why I get two outputs with the du command? The first one gave me one. I also didn't ask for the second directory so why did it give that directory?

$ du -h "/media/Part 1/Desktop/playlist"
775M    /media/Part 1/Desktop/playlist
$ du -h "/media/Part 1/Bob_5-22-2010/Desktop/"
863M    /media/Part 1/Bob_5-22-2010/Desktop/playlist
863M    /media/Part 1/Bob_5-22-2010/Desktop/

Probably because in the first case you had no subdirectory under "/media/Part 1/Desktop/playlist" but in the second case had a subdirectory under "/media/Part 1/Bob_5-22-2010/Desktop/".
