Nose to stone, Wearing smooth, Casting sparks, Dirty moves?

I'm not the main attraction, I'm not the main reason you're here, But still I'll entertain you, and hopefully I'll still make you cheer, Add a shortened version of Robert to me, and in many yellow hearts, I strike fear, But more fear in one, not the main yellow man, but his spanish-speaking son, but he already knows to steer clear

Woooah! We're halfway there! Woah-OAH! Halfway through a prayer! Take a pause! We'll still make it I swear! Woah-OAH! Half a sec to spare!?

I'm power, just ask any schoolteacher you know, More importantly, I'm something so special, that no matter what debts you owe, No one can steal me away from you, value much greater than gold, Though not as precious as wisdom, for that I'd sell my soul

I sound like taxi stuff, But I'm kraut and slaw, Bubble and squeak, Rolled rice and beef, Maybe kimchi, raw?
