I'm referring to that group chant that starts at 2:43. "IS THIS WHAT YOU WANTED, CUZ NOW WERE BROKEN". I'm not exactly sure what harmonies are.
the harmonies were the background vocals singing different notes beneath the lead vocals. personally, I though the harmonies were the cheesier part. It took the song to way-too-poppy of levels. Not that I'm against pop or harmonies by any means, but a band like this shouldn't have verses and choruses with so many harmonies that it sounds like the end of an NSYNC song. I actually though the gang vocals was the coolest part, especially coming off of how heavily the bridge built up.
