This document discusses various audio formats including terrestrial radio, digital audio broadcasting, recorded music, podcasts, and internet radio. It also compares CDs and MP3s, noting that CD sales decreased between 2008 and 2015 due to the rise of digital music, as digital formats allow music to be accessed more easily and cheaply without the risk of scratches or damage. While CDs generally have higher audio quality, MP3s offer portability and the ability to store more music due to their compressed file size, though transferring music to MP3 players can sometimes be challenging.
