Just test out the music that you are mixing before you actually start .. dont just get any two old cd's because you need to see whether the beats will go together .. for example you cant have 2 completely different types of music.. like Rock and Hip Hop .. as Eminem showed us with " Cleaning Out my vloset " or whatever its called .. just try it you might aswell , if it doesent work out for you then post again and ill try and help out aight .
