Not sure if this is appropriate post here, but can't figure out where else to put it. If I want to use my computer (Gateway desktop) to play music instead of my radio, how much electricity does that consume? I like to have classical music on in the background (great for the mood as well as keeping demons away). But our commercial classical station went off the air recently, leaving me only with Public, which I can't get in stereo (also they talk too much and it's only classical part of the time). I know there are hundreds of online options (I particularly like one from Finland), but I hesitate to make my computer my radio for fear of the electric bill, and also the toll on the computer. Good idea or bad?
