Is it usual to pronounce "betrayal" with two syllables ([bɪˈtreɪl]) instead of three ([bɪˈtreɪ.əl])? I'm asking because I've heard it pronounced like this in a song, which prevented me from recognizing the word. I wonder if its a colloquial pronunciation. If it's not, I'll assume it was pronounced that way in that particular song just for the sake of metrics.
