"Find all the latest tunes. Don't just go for general releases, go for album tunes as well, that will make your selection different from the rest."
DJ G.Child
It's different from a set you'll play in a club and will probably have a different vibe from any radio show you might do.
It needs a strong, attention-grabbing intro with your name in it and a steady stream of weighted tracks to keep the momentum going.
Remember, promoters will probably skip through it at some stage so make the middle and the end as strong as you can.
