Query: This is definitely a "back in the day" compilation

I highly recommend this book to any fan of the music genres charted in Billboard's R&B; Top 40. If you grew up on music like this, it's perfect for review during the years when you were in school--no matter if it was back in the 40s, 60s, 90s or 00s. You'll be surprised of all the music you have forgotten, you'll then find yourself looking for it to bring back fond memories.If, like me, you grew up during Hip-Hop's baby years (early 80s to early 90s), some great jams didn't make the top 40. Keep in mind that Hip-Hop from that period was not fully appreciated until recently, and Billboard recognized mostly Pop-Rap that crossed over like "Parents Just Don't Understand", "You Can't Touch This", "Wild Thing" or "Bust A Move" at that time. For those jams not on the list, you'll see the artist's music from the sophomore or third album (which happened to A Tribe Called Quest and Big Daddy Kane).
