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 te is NOT the lullaby. The fan liked the song so much, they used it as Bella's Lullaby, but it was never considered da Summit to use as the lullaby. River Flows In te was written da 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 ha rubato, stola da titolo 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 te da Yaruma?
well, i think carter wrote that one too...
