Lyrics are only one component of a track..
You gotta take into consideration the beat, instrumentals, the overall vibe of the song..the MC's delivery, emotion, voice, the way it sounds..
Poor Nelly, he always gettin the short end of the stick..but the truth is, even tho his lyrics may be mediocre, he makes up for it in all the other areas and thats why he sells millions of records and has a deal when there are lots of people who could write better shit than him who arent even signed..
As for 'hot in herre'..i cant really sit still when that song comes on, and i dont care what the hell he's sayin..cuz bottom line is, he sounds good, the music sounds good, and he got me movin..mission accomplished.
