@Linkat,
I'm sorry if I'm missing something but why not just use your smart-phone to do this? And then link to whatever source you want using it as the portal to stream music programs from the Internet? Most companies frown on and block using company resources to stream FM radio music playing..etc.
When I used to work as a Tech Writer, located in a cube farm, we could connect and stream an FM radio station whose signal was available...because we're part of the software developer network; however, that would drop every 20 mins or so also.
