TuneIn streams actual radio stations from your area–no FM tuner required–and from around the world, just in case you’re wondering what’s topping the charts in South Africa. A $4.99 Pro version lets you record songs.
What’s in it for tablets: In landscape mode, you get a category sidebar as you search for stations, and while you listen, a navigation panel lets you quickly switch stations and get recommendations.
