Jelli, which launched last year, is a user-controlled online streaming service – sort of a Digg for streaming music, or a group-controlled Pandora. Listeners vote songs up or down to create and alter the playlist.

Today they’re announcing an important business development deal – an actual radio station, Live 105 in San Francisco, will be using Jelli to set their playlists every weekday. Starting this Monday, every weekday from 8 pm to midnight, Jelli takes over.

Users don’t just vote songs up and down. They also get a limited number of Rockets and Bombs to move music more definitively up and down the list. And the chat area gets lively.

Bad news for those radio DJs.
