Hi,
thanks for the patch, good idea. However, slotStateChanged() isn't IMO the 
best place, because it can be called rather frequently (tens of times per a 
song) and might cause Solid going to sleep while the EngineController 
transitions to the next song.

Better approach would be to create a mini-object (RAII!) SleepInhibitor under 
playback/ that would connect to EngineController's playing(), stopped() (and 
paused()?) signals which should be less bumpy.

Would you mind improving the patch as suggested and posting it to 
http://reviewbard.kde.org/ ?
