Well. Music Mode is the app which I am using currently. I prefer it to any other app. The developer is very responsive and implements features really fast. Try it.
This is first time I am reading that someone is not impressed with Proshot. Ofcourse it has its problems but it knocks the official camera app out of park.
Here is one which very few people know:
Press Volume up and down simultaneously for three times and it will force close the app. But it works only when an app has been crashed so that you don't have to soft reset.
