Even movies can create distortion if you have the volume turned up too loud. You should be able to see a pattern here, it is the volume levels you are trying to achieve that will cause damage with a low powered receiver. Personally I forsee no problems as the 50W is enough to reach pretty loud levels, the M80s will reach ~91db on 1 watt and the M60s reach ~89db on that same watt. It is the peaks in the source material that create the need for higher power ratings.
