Playing audio through networked PC

hi i have a server setup in my living room behind my tv. Its mainly used to host personal files to share with friends. It also has a bluetooth dongle so people can send files via bluetooth that are automaticly put on the WWW folder on teh web server. These were the main reasons i choose for putting it in the living room. Now i was wondering if i could use the pc in my bedroom to pick tunes from my pc and then have them played on the speakers in the living room.

just so you know the pc in the living room has no screen and all actions are done via remote desktop

any help would be awsome id really liek to get this working.....
