Some styles have pushes built in them by design. Some do not. Using pushes, holds and shots can spice up a backing track. It will help break up the monotony of a repeating section or chorus etc.

Starting a song with a few instruments only will also help the song "build" over time by adding in more later on.

Using a different (similar) style in a section or two will also spice it up.

The key is using a style close to the original song when doing a cover, IMO. If you are using Biab every day, the styles will naturally get stale to us after a while. However, if you are gigging, the audience will never be able to tell the style has been played 1,289,429 times.

My advice would be to try the chord and bar settings for those pushes, shots etc . . .
