Occasionally, I want to listen to music that differs from my usual go-to artists. When I find myself in this situation I turn to my old friend: Grooveshark. Grooveshark has a ’smart playlist’ labeled Popular, which I find incredibly useful when I’m in no particular mood and want to listen to something new. I open up the Popular playlist, click “Play All” and then turn on shuffle. It’s a sure way to run into some of your favorite songs while broadening your horizons; and remember, Grooveshark does NOT play ads. Get to it! Groove Roulette.
