I'm in church band. Band leader gives a set of songs to practice. After rehearsal, they decide which four songs out of the 11 they want to play on Sunday and the key they want to play in. This is really annoying sometimes as some songs are really weird to transpose,and those songs tend to take a bit to get down versus your generic 1 6 4 5 songs. Worst of all sheet music isn't always available.
