Pandora Radio or similar apps, you don’t explore by inputting artists that you already like. You start off by selecting a certain number of beats per minute, and from that a web of songs and artists springs forth, always expanding as you explore. It’s very novel, and generally interesting to mess around with even if electronica isn’t really your bag. It gives you much more of a sense that you’re actually exploring and discovering, which is awesome. Just make sure you switch the language to English from the options menu.
