In a year or two, the #YouTube#music app as an experiment will be considered a #fail and will be shut down. YouTube will then bring good music player controls (video queuing, skip next etc) to their video app. Till then we suffer.
Watching Galaxymphony [youtu.be]. Great sci-fi music played by the Danish Symphony Orchestra. Very well orchestrated and great list of tracks.
A Space Odyssey
Just to name a few :D
