Audio files

So I wanted a specific audio file from NPR, it is David Sedaris' Santaland Diaries. There are other recordings of it that I could buy, but I liked the music in this NPR version, so I had to figure out a way to download a streaming audio file. I used the iRecordMusic program for Macs and it converted the streaming audio to an MP3. I believe what I downloaded was a free demo, but it served my purpose for now.
