does anyone know why in the twilight movie they didn't use the real bella's lullaby??

They did use the lullaby. Carter Burwell wrote it. River Flows in Ты is NOT the lullaby. The Фаны liked the song so much, they used it as Bella's Lullaby, but it was never considered by Summit to use as the lullaby. River Flows In Ты was written by Yiruma, a japanese composer

because their stupid ! , they didnt want to use the one that we all like they used the carter one which frankly doesnt sound like its really trying to tell her he loves her

they did actually da river flows in u just украл, палантин da Название cuz ppl liked it

i dunno
maybe coz robert couldnt play it well enough?
what was the 'real bella's lullaby' anyway?
River Flows in Ты by Yaruma?
well, i think carter wrote that one too...
