How many songs are freestyled on a alblum

just maybe 2 or 3 maybe 1

depends on what you consider "freestyle". I consider freestyle anything that hasn't ever been written. Many artists write so much that it's inbedded into the memory so they can spit it "off the top" like it's a freestyle when it's really previous scattered written material. If an artist refers to specific physical thinks when on stage or in the booth then it's freestyle to me. There has to be proof it's freestyle when it's heard. So I would say 90% of albums contain no freestyle. Not many rappers can sell a song of freestyles. Need hot beats and catchy hooks. 16 bars and a hook, over and over!!!
