I don't know if music software technically falls under "HTPC" but it seemed to be in the right area. I have an AVR hooked up to some decent speakers and I want to get my music out of it. The AVR supports DLNA as well as having the usual audio inputs. I used to subscribe to Xbox Music but they restrict everything from playing over DLNA devices and I don't want to leave my tablet wired to the AVR all the time, so away with them. Mostly I'm just impulse-buying music from Amazon which downloads as MP3s to my desktop. I want to be able to create and manage playlists easily. That is my biggest requirement. So I'm really looking for some software that I can run on my desktop which will stream over DLNA and which I can access over HTTP from my tablet over my home network. I'm totally willing to spend money if the best solution is proprietary or hardware. But I'm very comfortable with both GNU/Linux and Windows, so there must be something out there that works and has a nice interface. Suggestions? What do others here use?
