The only time this ever works for me is if I am feeling particularly 'relaxed', aided by some type of alcohol or another. This is the best time, as it's not uncommon for Every Time I Die or someone of a similar ilk to scream for me a discordant lullaby. Of course, all this could be avoided by simply not listening to music in the first place, but where's the fun in that?
This song below is by Kyuss, the stoner/desert rock band featuring Josh Homme and Nick Oliveri before they went on to form Queens Of The Stone Age. This is a nice, mellow tune which evokes the Californian desert, Monument Valley, sunsets and endless stretches of highway. Not a bad image for one to drift off to. It's from their acclaimed album 'Welcome To Sky Valley'.
