it is pronounced 'brr-ew-tal' the Ü denotes an 'ooh' or 'ewh' sound as it being a rounded vowel. unlike how brutal is normally prnounced 'br-oo-tal'.Gimmi. A. Burger said:BRÜTAL LEGEND! YEEEEAAAH!
(Erhm: Its pronounced "Brytal", not "Brutal", hence the "Ü"... Tsk tsk tsk.)
the way you have it spelt is misleading and would make it sound like you are saying it as 'Br-i-tal'.
