And if you're really a perfectionist, you could probably hear artifacting in the clapping.

I'm with you on this one. Concert performances are the most critical to encode at high bit rates, for precisely this reason. Noisy high frequency sounds with a lot of randomness (applause being the best example of this) are the hardest to encode well and will show the artifacts most strongly. You could have a song where most of the music sounds fine, but the audience sounds like they're applauding from underneath 50 feet of water.
