As much as we can be fans of particular artists, or love to see what an artist can do for themselves on their albums...you just can't deny a good feature or guest spot from another artist. What makes a "Feature" a best to me doesn't necessarily mean someone gets Eminem'd on their own shit, sometimes it's just the added energy to the track. Other times it's the impression that feature leaves and what extra push that guest spot gives the track [on or off the song]. Hit the jump to see what artists and which of their verses were my "Best of 2012"
