Help me choose a song for my lit class

for my intro to lit class, we've got to bring in a song that has a recognizable sense of voice, tone, sound, etc. i've been going through my itunes trying to find something but am struggling. i want to do something along the lines of rap (probably keep cursing to a minimum) because i feel not many others in my class will do it and its my favorite genre of music. the best idea i've got so far is lil wayne's "tie my hands" off the carter 3. i'll take any suggestions. thanks
