Also, for the record, that wasn't the question I was trying to forestall with my last paragraph. I was more after someone doing something bizarre like creating a multi-hour "song" where each "instrument" is a full other song loaded as one big sample or something. Generally speaking the answer to this sort of trickery is "You're a programmer, and you're using thought processes designed to slip things past computers. Judges are human." There are certainly ways to "slip things past" a human judge as well, but they are very different. Human judges generally react poorly to outright sophistry, where computers don't mind it one bit.
