Error Prevention - One of the errors that a user might make is to click on a genre without knowing that the user is voting for that genre to be featured at the party. This may be rectified by showing the user a small balloon tool tip that explain the info-graphic.
Design #3 
David arrives on the splash page of Remote Playlist and types in the name of the party he is going to this weekend.
He is greeted with a short description about the party including a small map of where the party will be hosted. There are three tabs on the right that allow David to navigate the website. The Event tab, which is currently activated, displays the event information. The Music tab displays the playlist. The Upload tab allows the user to upload their own music. David, curious about the music available at the party, clicks the Music tab (note: the Playlist button also functions the same as the Music tab)
Now, the party information is displayed underneath the header. David sees several tags for different songs. Each tag has a "star" on the top right which is the way a user indicates his vote. To play a song, the user clicks an arrow on the bottom right which pulls down playback controls for that song. There's an extra tag that acts as a placeholder with the label "upload your song." The "upload your song" also functions at the Upload tab (not display on this sketch).
Design #4
For the following design, the title page will consist of a search box on the bottom, a dynamic view of search results,and a series of tabs on the left hand side for top party searches. The purpose of the top party searches tab is to enhance user efficiency by gathering data on search history, and providing the top 5 searches as quick access options. An autocomplete functionality for the search box will help prevent user typos and errors. In addition, an upload music button will be constantly present on the bottom of the page. With its pop-up functionality, the idea is to enable the user to upload music to the site while still being able to download, vote, and listen to music. As the user finds his playlist among the list of user searches, he will click on the link as soon as he or she finds a desired match. The page will shift to the second window, in which the active playlist is now shown. The playlist here can be organized by rank, title, and the artist, and provides a range of different functionalities. The play button allows the user to play the particular song. The yes/ no button is used to allow user feedback on a song's popularity, which will determine its relative ranking in the song list. In addition, a download button will be added to the rightmost section of each song.
