Pandora Radio If you don't know Pandora you're living in a hole. This free app allows you to take the best of the radio and leave the rest out. Customize your radio experience by picking songs or artists to base your song selection on. Great app and likely should be on any phone.

Slacker Radio Just like Pandora but with (apparently) 4 times the music. Not sure how that's possible since Pandora has a TON of music but if it's actually true you may well find that obscure artist you love.

Virgin Radio Italy I'm not sure why I want to include this but having access to other countries radio is just awesome. Radio was one of the first ways to communicate beyond written word so I guess reaching out to far off lands makes this particularly interesting. And hey, maybe Italy celebrates Radio Day too?

Public Radio Player Love your public radio? This app gives you just that, and everyone else's public radio too. On your phone for the win!
