Refresh your ears
Internet radio apps are awesome for exposing tired ears to new music. But even with the endless number of tunes, at some point, these high-tech stations start to repeat the same songs over and over. Nostalgia for good ol' AM/FM sets in. TuneIn, a free app, accesses local and worldwide radio stations (yes, they still exist) and plays them through your iAccessory (or, also, via your desktop or laptop). Walk the dog and listen to some NPR without having to lug around an actual radio. http://tunein.com.
