Eminem is my guilty pleasure, and that is sort of embarrassing, NOT because I'm 45 years old - he is after all middle-aged himself - but because it makes me feel like all the people who discovered blues through the Rolling Stones, and rock music thanks to Elvis Presley. I. e. a bit pathetic.
At my age, however, I can live with that! Especially as it allows me to vicariously feel like the angry young man Eminem somehow seems to have managed to remain.
An eminent sense of poetry and "rapbot" rhythm ("I rap like a robot").
What's not to like?
