Mack Maine is one of the most instrumental members of YMCMB, and has been for a while. Not necessarily because of his lyrical prowess, or the numbers of records he’s sold, but because he provides a strong business backbone to the label. This doesn’t mean however he’s not capable of putting out a surprising track here and there. I’ve never particularly been a huge Mack Maine fan, but when I heard the song ‘Windows Half Way Down’, I was impressed. Check the method below.
