I'm a student that has always had trouble memorizing vocabulary words... I got the equivalent of a 710 Critical Reading on the PSAT, and one of my weaknesses is vocabulary, which makes me lose around 20-40 points. It's just ridiculously boring and I forget the words a week later anyways, but I was introduced to new methods of memorization with Rock the SAT, the first book I bought. But Rock the SAT presented 2 problems: the vocabulary was fairly basic, and the singer's voice was extremely annoying.
Having memorized all the words in Rock the SAT, I went to my local store to find Vocab Rock, the only other book like Rock the SAT that I knew about. But when I flipped through it, I saw that the vocabulary was extremely easy and few in number. Fortunately, I noticed Flocabulary and looked through it. There was an incredible amount of vocabulary crammed into each song, and the lyrics looked provocative and interesting, and most importantly, i didn't know about 1/2 of the words. Amazed, I purchased it.
When I put the CD into the CD player in my car on the way home, I thought the radio was accidentally on, since the music was so well-produced, the lyrics were intelligent, and the rappers actually had an extremely well developed sense of musicality. I could barely believe my ears when the song began to recite vocabulary flawlessly.
If you are looking for a music vocabulary CD, this one definitely is the best, unless you hate rap with a passion. The only problem I found with rap was that as a rock listener, it was more difficult to memorize the lyrics, because there was so much packed in. I wouldn't have it any other way though, it's better than feeling like you are wasting your time while a song rambled on about the definitions of "parallel" and "mosaic" for 3 minutes. And with all music vocabulary CD's, it is important to look at the book's lyrics while listening, since the mind tends to gloss over words it doesn't understand/hasn't heard before as random syllables.
