Alright, I have a laptop with wireless integrated. It is connected to a wireless router wirelessly. I have a 360, and it is connected to the same router wirelessly (i have the wireless adapter)

How can i listen to the music on my laptop, on my 360 without using wires or cables?

I have done it before with a pc, but the pc was connected to the router with a cable, and the 360 was still wireless.
