The second decade of the 21st century has continued to usher in new technologies and devices built on the technological foundation established in the previous decade. Technologically speaking, our personal devices and lives have evolved symbiotically, with the personal computer at the center of our daily communications, entertainment, and education. What has changed is accessibility and versatility; users can now perform the same functions and activities of their personal computer on a wide range of devices: smartphones, tablets, and even more recently, smart watches. The increase in personal computing capacity has a profound impact on the way people listen to, promote, and create music.
