Images - DJ Interface	Description
	For the home page, we opted for a simple look. Since login was not part of the previous design process, we simply mocked it up and implemented it. While testing internally, we found that it would be good to give the user feedback immediately about the validity of their input.

Images - Listener Interface	Description
	When a user initially opens the application, they see this default home page. They are prompted to "submit a dj code." This screen was created after the entire app was completed. It's simply a less detailed version of the home screen that we previously developed (explained in the next image). Initially, this screen kept the rating buttons, but after the user testing period, we decided to remove them. Also, to make it easier for users, we made the DJ code case insensitive.
	After submitting a valid "DJ code," information begins to populate the app. The user can see the name of the song currently playing and "rate" it either up or down. There is also a "tweet" button that would allow the listener to tweet about the event. There is also a navigation bar to let the user move between the other screens. The main goal for this page was to make it as simple as possible. After the heuristic evaluations, we decided to change "rate this song" to "rate this party" in an attempt to give users a better understanding of what exactly they were rating. After submitting the dj code, we initially left it on the screen, but after doing the user tests, we decided to remove it.
	In this screen, the user sees the list of songs that have been played. When the user clicks on a song (i.e. after clicking on "Lights"), the selection expands, showing the album cover, the artist, and the genre. Initially, we planned on presenting as much information on the song as possible. However, after the heuristic evaluations, we decided to remove most of the information (like year produced, record label, etc.).
	This is the voting screen. When the DJ selects songs for the listeners to vote from, they are shown here. Each voting option shows the name of the song, the artist, and the current number of votes.
