From going on road trips to dancing at parties, music is a big part of the social experience. However, playing songs you want to hear has always been a hassle. During road trips, you have to constantly switch the aux cable between your friends so each person gets to play their favorite songs. At parties, you have to go up to the DJ and yell your song requests into his ear. Even so, he might still forget your request and you never get to hear "your song". The simple idea behind shared playlists is having one playlist that many people can access and add their songs to. The owner can choose who to send this playlist to, who can listen to it, and who can edit it.
