It makes sense with a smartphone to listen to lots of audio content. Audio content for many users isn't limited to music though. Podcasts are a big thing for many smartphone users and Google has unveiled a way to find even more podcasts to enjoy from your Android device. Google has announced Google Listen, described as an audio search engine and it acts as a podcast manager. Using the app, you can subscribe to audio feeds and download new content over the air. The app has its own search bar where you can enter a term for a type of podcast you are looking for.
