What's going on here?

I've been inspired by the few reviews that these tracks have received to post a little explanation. Before I do that, however, I would like to thank those of you who have taken the time to listen and provide feedback: I really appreciate it. Anyway...

Both reviews that have been posted so far reference the somewhat incongruous drum machine spatterings behind the tracks. One mentioned popping popcorn, and the other questioned whether they were experimental or last minute (and perhaps even a year behind the times).
