Music really IS powerful - for mood, for energy, for concentration - and even for creativity. I usually write with Focus@Will - headphones a must! (AlphaChill at a medium pace for me). Workouts are with my favorite DJ David Olam (MixCrate) (a friend - I'll be posting about his creations soon). Driving - podcasts or Dave Matthews Band (that sounds like an odd pairing!). Even sleeping, we have music - ambient usually, or else hypnosis tracks.
