If you’re still using Pandora, you’re wasting your time with commericals. Songza is a free, commercial-free app. While Pandora plays songs based on specified artists, Songza aims for genres of music based on your mood and activity.
Once you picked what you’re doing (Waking up Happy, Drinking Gourmet Coffee, Working Out…etc.) it takes you through a few more music preferences (country, rap, pop…etc.) and then creates commercial-free listening for hours on end. Who know how long this app will be commercial-free, but I was getting tired of Pandora’s increasing amount of interruptions.
