Is there alliteration in "I'm Yours" by Jason Mraz?

In "I'm Yours," a love song by Jason Mraz, alliteration is used sporadically.

There is quite a bit of repetition in the song, as in most songs.  Repetition is when a word is repeated.  However, some alliteration is also used.  Alliteration is when the initial sounds at the beginning of a word are repeated, such as in tongue twisters like she sells shells by the sea shore.

Here is an example of alliteration.

In "I'm Yours," a love song by Jason Mraz, alliteration is used sporadically.

There is quite a bit of repetition in the song, as in most songs.  Repetition is when a word is repeated.  However, some alliteration is also used.  Alliteration is when the initial sounds at the beginning of a word are repeated, such as in tongue twisters like she sells shells by the sea shore.

Here is an example of alliteration.

Listen to the music of the moment, people dance and sing, we're just one big family
And it's our God-forsaken right to be loved, loved, loved, loved, loved

In these lines, the words “music” and “moment” are examples of alliteration because the initial “m” sound is the same.

This helps to create the musical quality of the song, in addition to the repetition of the word “loved” at the end of the line, and that is why song writers us alliteration.  Alliteration is used again later in the song.

I've been spending way too long checking my tongue in the mirror
And bending over backwards just to try to see it clearer
But my breath fogged up the glass
And so I drew a new face and I laughed.

The alliteration of “bending over backwards” and the rhyme of “mirror” and “clearer” along with “glass and laughed” are all sound effects used in this song.  The fact that alliteration is used only in a few places means that it is not the main contributor to the sound.  Most of the song's sound comes from rhyme and repetition.
