Overview

Description

Social music app (playing music, playlists, finding songs) where you can see what other people are listening to live

App Evaluation

• Category: Entertainment/Social Networking
• Mobile: Easier to use to connect with other people through music
• Story: Allows users to find songs, build playlists, and see what their friends are listening to
• Market: Anyone who listens to music
• Habit: People listen to music throughout the day when they run errands / work out / etc, so it will be habit forming
• Scope: Can start out initially as a music-focused app with traditional music app capabilities (find songs, create/edit playlists, like/unlike songs, shuffle/play/pause) and an instagram-style social feed of friends and the music they are listening to
