Song: Kanye West, "Dark Fantasy"
Product: Serato Scratch Live

Serato ushered in the era of the digital DJ by making it possible to spin a laptop full of mp3's on your tried and trusted Technics. While few remain loyal to wax and lugging crates, the convenience of using Serato has attracted the majority of today's DJs. That said: If you don't have a new Yeezy track on your hard drive, maybe it's time to find a new line of work.
