Is it allowed to listen to music while at the commands of an aircraft?

Sure.

Is so, do you?

Sometimes. We have an intercom with two music inputs, so rear
seat and front seat can listen to different music. If the intercom
is set to 'all' music will cut out for every radio reception
(and I want it that way), so if we're flying in a high-radio-traffic
area I usually don't bother. On routes and times where we can fly
for hours and without hearing another soul on freq (except for me,
asking ATC for occasional radio checks to make sure I've not lost
them) it's great. We have a little MP3 player which can hold
something like 8-9 hrs of music, so I don't have to fiddle with
changing CDs or the like.

What else do you do during long flights once auto-pilot is engaged?
Do you just take time to watch the landscapes?

Landscapes, don't forget scanning for other traffic. That's the
part that's hard to keep up when the sky is 99.9% empty of other
traffic at your altitude.
