Recently someone who had listened to @turntablez' September mix told me it changed his whole outlook on his very crappy day and put him in an incredibly good mood after listening. When I first heard July's mix it was during the deepest depression of my life, on a morning when I hadn't slept in days due to an ongoing issue with insomnia, and it had a similar effect - I felt hopeful, happy, and cheerful for the first time in weeks. The power of music and a great DJ can't be underestimated - it literally changed my life!
