To my opinion it doesn't matter to much what you are listening to while cooking, as long as it is your music and no radio music, so you can be sure you will enjoy every single track you are listening to. You can easily use your shuffle and it doesn't matter whether classic, jazz, folk, metal...... pops up, you will adapt immediately, its your music! If you prefer to choose the music yourself and let not the shuffle decide for you, make sure the music doesn't take your complete concentration, like the Goldberg Variations played by Gould. Choose something which allowes you to concentrate on cooking, nevertheless it should make you happy. I like to listen to an interpretation of the Goldberg Variation by the Canadian Brass (it don't requires your concentration this much), for example. It is different while you are eating. Here one really has to dicide the music played very carefully, no way of shuffling the playlist. It shouldn't be off-beat music(I think it is not a good idea to start noding while eating). Off course metal isn't a good idea than as well (head banging while eating is quite challenging). I thing something smooth is perfect. Something in between Jazz and Classic, for example. I for myself found Jaques Loussier the perfect attendant for eating (gives you again a possibility to listen to the Goldberg Variations in a very different interpretation). But of course this is my way and everybody has to find his way!
