Lullaby is a Chrome add-on developed by Matt Runkle that provides a sleep timer for streaming web services. This program is designed for individuals who enjoy listening to music as they fall asleep, but find that streaming music services continue playing indefinitely. With Lullaby, users can now control how long their music plays, allowing them to pause their stream after they have drifted off to dreamland.

Lullaby currently supports popular streaming music services such as 8tracks, Google Music, Grooveshark, Pandora, Rdio, and Songza. To enable the sleep timer, simply click on the Lullaby icon in the omnibar and select a timeout length. Lullaby also provides a helpful warning by alerting users five minutes before the player is paused.
