Analysis 3: You Don't Know You're Beautiful - One Direction

Theme Variety:  Very simple, verse, chorus, verse, chorus, "nana" chorus, verse, broken down chorus, final chorus, or something close to that.  I-IV-V throughout.  Guitar, synth, voice harmony (but never five part... suspicious??), bass, basically your typical boy band, but younger.  Gets boring quickly.
Stars:  4

Music Complexity:  Simple chords, as mentioned above.  Guitar, drums, and synth strings almost overwhelm the refrain.  During the verses, guitar is too loud, and the drums should sue the drummer for abusive behavior.  Main difference between chorus and verse is lack of synth strings and longer guitar chords, as opposed to the shorter strums during the verse.  For their age, not bad, but lacking compared to older musicians.
Stars:  6.5

Dynamic Variety:  Two settings:  verse, and chorus.  Verse, is "softer" only because it lacks an instrument and the chords are shorter.  Not very interesting dynamic wise.
Stars:  3

Singer Talent:  There are some harmonies, though never a five-part, and not even a four-part, I don't think.  Melodies are very repetitive.
Stars:  4.5

Perceptible Auto-tune:  LOTS of auto-tune.  They hide it well, with multiple people singing, but - especially during the broken down chorus - it is definitely there.  Its a bit shameful they didn't wait till they were better singers.

Lyrics:  Superficial lyrics.  It is exactly what every girl wants to hear: she's beautiful, don't be so shy, etc.  I also heard a big no-no:  singing about the song they're singing.  In all the songs I've listened to, I've heard one that does that well, "I'll have to say I love you in song" by Jim Croce.  All others seemed very...I don't know how to describe it.  But it's like they're bragging that they wrote a song.  EDIT:  A friend of mine pointed out another artist mentioning his own song well;  Your Song, by Elton John
Stars:  5

Overall:  A boy band song.  Okay for little girls, but not really that great, in my opinion.  I'm surprised it made the top ten.  I suppose the lyrics are easy enough to sing along with, if only because they're so repetitive.
