Streaming music

• Consider the scenario
• Not focusing on the actual music being streamed
• More interested on the user(s)
  • Interactions

  • Other details

Interactions

Primary questions

• What?
• When?
• Where?

• Like / Don't play
• Next / Previous / Skip
• Select Channel / Playlist

How to store data

• Data is archived as a log
• Sent as interactions occur
• Number of interactions will vary considerably between users
• Logged data can be analyzed later on

Analytics

• What about preferences?
  • Can be obtained from logged data
  • Favorite genres, bands, etc
  • Most popular times of day
• Other details?
  • Most popular app platform / version
