Should I listen to music while I jog? (long-term)

Music gets me pumped so I can jog/work out harder but I'm afraid that in the long-term:

1. eventually the music will get stale and my jogs/work outs will suffer as I effectively have less energy
2. music will distract me and not allowing me to focus on the jog/work out

Also, do professional athletes listen to music as they train? Why or why not?
