Replying to Duets-the final chapter

i just bought this album(yes, bought) and i'm a little dissappointed.  I mean it's really good, but i was expecting more of biggie rapping, caus he's the shit, i diddn't realize that it was more of just a tribute to him, with a bunch of rappers that aren't as good as him rapping and like a minute of him at the beginning of each song. just thought i'd say that.  This isn't to say that they're aren't some sick songs on there though.
