Turntable of Turntable.fm fame today launched a new radio app, featuring songs that are hand-picked by friends and other app users. While Turntable.fm is designed for chatting with other users while listening to music, Piki builds playlists based on the preferences of others. The app allows users to pick a song, which is then incorporated into the radio playlists of followers, creating unique song lists that are created via user-based preference rather an algorithm. In addition to building a playlist based on songs chosen by users, the app allows for specific genres and artists to be chosen to narrow down the selection field. Comments can also be added to songs and shared among users. Piki can be downloaded from the App Store for free. [Direct Link] Article Link: Turntable Launches People-Powered Radio App 'Piki'
