This may sound a tad esoteric, but hey, music can be that way. When I practice examples with the metronome, I see it as meditative. I really enjoy working with the metronome as I find it to be calming, relaxing, and enjoy the focus it takes keeps my mind clear. I've spoken to my friends who are serious practicing meditators and how similar an experience it is when they meditate and I practice with a metronome for long periods of time. I know many musicians feel this way as well. I love the feeling of calm I have after a good practice session. The odd thing is I often have to remind myself how much I enjoy practicing.
