Hmm, I just had a look at that spotify, never heard of it before looks cool. Found this on some Sweedish website, might be of some help:
Game:
The latest generation of game consoles and many other media players are equipped with the function to play media from a UPnP server. Some UPnP servers such as TVersity can also connect to the internet radio and streaming music to further your game console (or media player, or computer. To use this function, your game console to support UPnP, and it requires some software on your computer with Spotify.
Configure your sound card so that the "stereo mix" or similar is to choose which input device. Alternatively you can use
Virtual Audio Cable to connect your line out to line-in without cables. In the worst case, it is possible to use a 3.5mm stereo male-male between the sound card's line-out and line-in jack.
Install the
SHOUTcast DNAS server or
Icecast. Change password for higher security (shoutcast use "changeme" by default).
Install (
Winamp +
SHOUTcast Radio DSP plug-in) OR
edcast stand alone. Configure program to stream audio from your line-in device (such as the stereo mix) to the radio server, if it works will dB-meter on the move in time with the music. Set the program to stream audio as mp3 in the desired bitrate. Make private stream (avbocka audience), enter password and connect to the radio server. Try to connect to the server ( "http://localhost:8000/" on shoutcast DNAS).
Installing the UPnP Server that can connect to webradiokanaler (eg TVersity) and add your radio ( "internet audio" on TVersity). For shoutcast DNAS is the address "
http://localhost:8000/listen.pls".
Start the game or media player and connect to the UPnP server
It requires a lot of work, can not use the control pad to change the song (but you can use the wireless controller to your computer with spotify), the sound may be a delay of 7-15 seconds, but it works well and you can play music from spotify on your game (preferably connected to your home theater). At some point I experienced a rather brutal echo, but it disappeared when I started and made a new attempt. Start the game console last to minimize the delay. If something hangs and the delay becomes too great, restart the UPnP server and game and try again.
Doesnt make much sense to me lol
