From the developer:
Until AM for Chrome offers a full-fledged DJ setup in a lightweight packaged app. Possibilities include vinyl scratching with two turntables, playback speed adjustment, sound modification through effects and more. You can use the music from the cloud while online or keep the party going with your locally stored songs even when you're playing at a venue with an unstable internet connection.
