To you the truth, em's single COMBINED with the beat was the best part of the song, dre lyrics are easily replaceable. No really, no hating, dre's lyrics really were the weakest part because it sounds forced. I know ShadyVsEminem and some others are gonna say I'm saying that just to find something to throw dirt on Dre. But it does.
But while this one stands much more taller and more listenable than dre's previous singles for Detox, it doesn't take away from the his lackluster lyrics in the song. It really sounds forced and written by other people, listen to his flow and the way he's saying it closely. His lyrics don't sound like the regular Dre, how he was rapping either. That's because in his other albums before he did mostly his own lyrics and that's why they sounded like dre and not forced, that's why they flowed naturally. This song and the other singles just seem like all the artists he got to work on the album sat in the studio with him and decided with others what they lyrics would be until they all agreed on the final version.
I dunno whether he is writing his lyrics or not, but how he is rapping them just sounds weird.
