you also can use the cloaked links to embed objects. for example:
convert the url
http://music.armopride.com/Pink%20Floyd/1969%20-%20More/The%20Nile%20Song.mp3
when converted (in this case) its,
http://url.omfgesad.com/?u=PWyYC8c6LAXj2MEW-hj54q-x
you can embed that and it works as if it were using the actual link.(works for images too)
:D.......this seems a bit long for a simple explanation
