@king it makes them feel better. Rihanna does not rehersal she practices a song and it's a difference between rehersing and practicintg. One you go through the scales, work with notes and tunes something like that! Practicing, you listen to a particular thing and you copy and that's what Rihanna does, that's why she cant stop a song and pick up back up were she left it or adlib it to make it have more meaning cause she just cant...
