One of the biggest compliments a singer can get is at concerts when they take a break fom singing for a second and just listen to the crowd song their song, amirite?

I personally don't like that. When i go to a concert i expect the singer to be ready to sing one of their own songs.

I went to Ed Sheerans concert and he had the audience sing the background riff while he sang the main part. It was really cool.

I saw The Used recently, and they incorporated the crowd nicely. It was beautiful.
