Beats Music Creates a Personalized Playlist Based on the Time of Day, Location, Preferences, and Other Clues

Beats Music is a new music streaming service featuring over 20 million songs, sharing, and a search function that will let users browse songs and playlists by curator, genre, or activity. Why activity? Because it's one of the main criteria in the app's 'The Sentence' function.
The Sentence gives users the option to generate a continuous playlist based on their current location, activity, genre preference, and surroundings. Just answer a few questions and Beats Music does the rest. It's available now as a free download with a $9.99/month subscription (with a 7 day free trial, of course).
