Query: a master piece

I gotta say that I was very surprised when I read the reviews already existing because I didn't find them very helpful at all.To me, homework is certainly one of the best house music cds ever, and by far. For people that like hard house, rollin'& scratchin' is for you, it is just perfect! I don't know how people can like this cd but don't like this track, it s just awesome. It is a very eclectic cd, which takes you from the crowded beginning of the night with "around the world", and brings you to other places with "Rollin' & Scratchin'" passing by "Burnin'". All those tracks will make you dance all by yourself in your room, and will make you have the time of your life! Don't miss it, definitely a master piece..
