With a familiar, instant messenger feel, it's easy to get started with Slack. But the service became popular because of its wealth of advanced features, like customizable alerts and a Do Not Disturb function. You can even host VoIP calls through Slack with your coworkers. A free account will get you started, but a monthly fee unlocks even better search tools. And be sure to install the Giphy plugin for maximum productivity.
With its huge inventory of music, Spotify has become a mainstay for free, legal music streaming.
