If you actually listen to KoL, their early albums make references to Oklahoma. 'Slow Night, So Long' :
"She's opening up just like she really knows me
I hate her face but enjoy the company
I'll take you home, back to Oklahoma
You're not so nice but the sex sells so cheap"
But if you want to bash Oklahoma...there is a song by KoL called Talihina Sky with these lyrics
"But everybody says this place is beautiful
And you'd be so crazy to say goodbye
But everything's the same this town is pitiful
And I'll be gettin' out as soon as I can fly"
I love KoL for the record.
