Same here. TuneIn Radio is a keeper. I use it primarily for talk radio shows that I listen to. Other than that, I use Slacker and iTunes Radio apps. I've deleted Pandora.
I used to use Pandora and slacker daily. When the iPhone 5s came out with iTunes radio I never installed Pandora or slacker. iTunes radio for me has completely replaced any other streaming radio service. I use it both day and night
Spotify is my go-to app. But I use Tune-In for local radio stations. I do use ITunes Radio when I'm in the mood for specific genres. Those three cover all the bases for me. iTunes Radio is gorgeous to look at.
