I know that the albums can be damn boring by the same artist but if you mix em together and do a like best of CD, I can stay focused through entire collection. I just did a CD like that like a week ago and have songs like Hit Em Up, Regulators (great), Still Dree, Lay Low, Murder Was The Case, Check Yo Self, California Love, Gimme Some Mo, In Da Club...and I find it as pretty good music actally.

PS: Mike Portnoy (Dream Theater) adores rap besides The Simpsons.
