Great reuse of MPd/c instead of writing something else homemade.

I wonder why this isnt more easier, people love to listen to music, from various sources to various speakers, sometimes I want to play it perhaps on my phone whats available on the raspfi, and sometimes to play what is on the phone but not on the NAS/usb-stick through the raspfi connected speakers (without attaching wire to the phone), and this solution seems to falter here... and sometimes I would like to give control of the playlist to a friends phone, or play the music on his device through mine. Why are these scenarios so difficult to do, it is 2013 and we have all the pieces? And yet it is such a hassle. (How come everything sucks so much?)

Ive been trying for years now, without success. Its always some library or quirk thats missing. Tomahawk-player is the best I came so far, together with DLNA, but it doesnt have a good android client yet.
