Yes my brother, but I would consider 'Lyte as a Rock'
A simile because of the usage of the word 'as'

from MC Lyte – Lyte as a Rock Lyrics on Rap Genius

Meaning

In English literature, one may come across the term “simile”, which is a figure of speech involving the comparison of one thing with something else. It usually contains one of two words: “like” or “as”; hence why King of Chill insists that it is a simile.

In the end, both Milk and King of Chill are correct… because all similes are metaphors.

(That being said, not all metaphors are similes.)
