We beg to differ when it comes to Equal Sonic's "History Of Lyrics That Aren't Lyrics" viral video. If "Na na na NA NA NA NA, Hey Jude" isn't a lyric, than why is it showing up on our lyrics page? HMM?
Regardless of whether or not a "La la la" or a "Na na na" is a lyric, it's a definite hook, because anybody can sing along — regardless of what language you speak.
Which is your favorite "non-lyric" from the medley? Mine might be O-Zone with "Ma-ia-hii / Ma-ia-huu / Ma-ia-hoo / Ma-ia-haha" at 2:45...
