The beautiful middle ground between hauling crates of vinyl around to gigs and having every song in the universe on a small thumb stick. You get the feel and sound of spinning your old vinyl, but the DJ cd players can access your music in myriad ways. Cds, flash drives, mp3 players, tablets, and laptops all fit the bill as music storage devices.
DJ CD players also give you advanced controls, allowing for sequencing, looping, and on the fly editing. This lets you create music as you play it...something not really possible with turntables. With so many professional models to choose from, you'll be able to find a DJ media player that really fits your personal performance style.
