It has very pedestrian lyrics (how many times can you rhyme island with island?) and the vocals are terrible. The songs sound like they were written by a child and they talk down to you. I mean if you like mediocre song writing I guess it's great. Y'all have low standards I guess.
I don't know about worst, but I'm not a fan either. It sucks when songs rhyme a word with itself and the main song in the movie does that over and over... BOO!
What a ridiculous and objectively wrong claim. Yes, it uses "island" four times within three lines, but that is a device called "repetition", used for emphasis. Moana feels trapped and hemmed in by being on a island, and so, "island" hems in part of the song.
The song uses traditional ABAB rhymes, along with clever run of ABABABB.
The song also uses "assonance" in hammering the "eye" sound without being perfect rhymes. A device that is perfectly acceptable in poetry and a boat load of pop songs.
So, no, the main song doesn't give you a nursery rhyme where you get perfect ABAB rhymes from beginning to end, but that's what make the song a more mature song since it plays both within and outside the rules and breaks the rules at times.
Here's a breakdown of the rhymes, and it is objectively clear the song does *not* keep rhyming the same word with itself.
... water ... why
... daughter ... try
... take... track
... make ... back
... know... go
... be ... me
... knows... goes ... me
... know ... go
I know everybody on this island, seems so happy on this island
... design
I know everybody on this island has a role on this island
... mine
... pride... strong
... satisfied ... along
... inside ... song
... wrong... me
[assonance in red]
...
light ...
shines ...
blinding
... knows... goes
...
like ... to me, so ...
find me
... know... beyond that
line... cross that
line?
...
line ...
sky ... sea... me
... knows... goes
... sea ... me
... know,... go
Also, the song "Moana" sounds like it's repeating the same word at times, but it's a clever use of homphones: see, sea; leaves (of trees), (no one) leaves.
And talk about rhymes schemes, "Shiny" has some of the cleverest use of rhymes not found in any other song I can think of.
Anyone who thinks of the songs of Moana as hackneyed, needs to sue their High School for the failure to teach how to critically analyze poetry/lyrics.
