1. At the beginning of the mains, when everything is going easy, I prefer energetic music.(ever wonder what Aaron Neville's funkier brother does for fun? Or how about Brit-cum-New Orleans pianist Jon Cleary?) 2. During the middle drudgery of the crosses I prefer songs that have a steady train-like rhythm to keep me going. Especially so when a job used to take me more than an hour.(eg. this is on now. Or you can't beat JJ Cale to induce a trance-like state.) 3. And near the end, back to triumphant finale music.(how about ending in a light classical vein? )
