The main challenges we struggled with were the limitations of the Spotify API, which only supports the retrieval of basic user information. The frontend was created using HTML, CSS, and JS with Bootstrap and jQuery. We used express and ajax to facilitate the rendering of HTTP objects and dynamically coordinate routing and information sharing between group members. The web app itself is a Node.js app deployed on Heroku. getting a user's top songs) and read/write to the database. We created custom wrapper functions to make calls to the Spotify API (e.g. We stored group information, including user IDs, display names, and access tokens, in a secure Realtime Firebase Database. Finally, once the playlist has been generated, it is revealed to the group and automatically 'liked' to add it to their accounts. While building the list, spotifusion's loading page propagates to all members and suggests a random member's top song so groups can explore each other's music taste. Once everyone has joined the group, any user can select a length for the playlist and spotifusion begins generating your group's blended playlist using the Spotify API to access user data. The page dynamically loads to alert all users of who has joined the group, and syncs their progress in the web app. They can also join a group using the PIN.

Users can start a new group, which creates a unique PIN to share with friends. Users visit spotifusion's homepage and log in to their Spotify account, granting spotifusion access to their data. Spotifusion analyzes users' listening habits and determines favorite tracks that they have in common with their friend group. Music is a must but we all want a chance to hear music we love, without spending half the time creating the playlist ourselves. We wanted listen to music we all enjoy, especially in situations like these where we hack together for 24+ hours straight. Spotify recently came out with the Blended feature, but our group of friends wanted a way to make a blended playlist for all of us, with a few extra features too.
