If you find yourself on public transportation or a treadmill, Google Listen will help your tedium suck less. I do both more times than I want to each week but Google Listen helps me ignore it and move on. You can manually add a RSS Feed of a podcast or search to find new podcasts. You can see what others are searching for if you have no interests of your own and leech off the ideas of others. It can download over your provider's network but will automatically download podcasts on wifi networks when the sync runs. If you want to listen to podcasts to burn your time this is a great app to help you get past the boredom.
