I've got no experience with Amps at all, so please excuse my ignorance.
You might be surprised how little average power is needed. It's the peak levels in a signal that require a lot of power. At least 10 times for music I think. THX reference level calls for 100 times peak to average power! (Movies are much more dynamic than most music.)
I would say the most dangerous music for speakers is modern rock, pop and rap music that's highly compressed. Highly compressed music gives the speaker drivers less of a rest. In that case, I feel it's not the amp that's the problem but the music itself and the ear damaging levels being listened to
In conclusion, I would say most people will never damage speakers due to having too much amp power. Having too little power paradoxically can cause problems if (a) the amp/receiver is strong enough to do damage when it's clipping and (b) you have no regard for what's coming out of the speakers ( I would think there would be some warning you were overdriving the amp/receiver from the reduction in sound quality.)
I have blown one home audio speaker in my life. I was trying to get sound loud enough to be heard outside. I was clearly overdriving the Yamaha receiver in question, that was not designed for such use, with bookshelf speakers of moderate sensitivity. I feel that was all my fault (and Klipsch kindly replaced the unit, no questions asked.)
