Just to put some context around the value of posting description with audio clips, especially since your original file was over 7 megabytes long, it's nice to have a sense of what the clip is about before spending the time downloading, loading it up and listening. I generally don't listen to every clip posted, even though I assume each poster thinks his or her clip is "interesting." A good description lets me screen for the ones that might interest me, and also helps set the scene beforehand, which can make it easier to understand the audio as it goes by the first time.
