iTunes Radio bug..

Has anyone noticed that when streaming iTunes radio in the car over bluetooth there are some issues..

#1 - Sometimes when I hit the next track button on my steering wheel to skip to the next song, it won't go. I try doing it from the lock screen and it still won't go. I have to unlock my phone and open the radio app to skip.

#2 - Sometimes if an alarm goes off on my phone, the music won't start playing again automatically once I dismiss the alarm.

#3 - Sometimes when I get in the car it won't start playing the radio automatically.

I NEVER had any of these issues with the iPod app in IOS6. I'm not sure if this is isolated to iTunes radio or a problem with other audio apps in ios7 as well.
