Do I have to?

[SwurVe]

If I am using an rap instrumental already from another song that was made by some of the top producers....I know I have to still mix vocals...But do I still have to eq the beat??? or has it already been done? cause usually I just mix vocals and leave the beat exactly how it is since it has already been made by another producer..

Depends on what you want to do and if the beat fits the sound you want....
