In one word... Magnificent!

This app is awesome.
Backrounding works in OS4, unlike others, and best of all, its free.

Being the CEO of a radio staion, having this app to hear my station on the go is far higher the awesome, and I can use the buffer feature to hear myself after I do some talking on the station, I might sound full of myself but this is really great.

If you dont have this app, get it.
Seriously.
