This song is "God Make It Not So" by teen rock/pop band Hover:
"They said we got the call around 2:00 this morning.
Another roadside (?) killed our boys today.
It's your brother, he's gone away.
He's with the Lord I pray.
He held my mama's hand as tears ran down her face."
The word is pronounced "KOW-ler"
