Hooks are nothing but the choruses that are included along with the rap instruments. These are popularly known as rap instruments with hooks. There are many websites that create rap instruments with hooks for artists. The producers would have written a smash hit for artists and it is up to the artists to fill up the gaps found in the rap instruments with hooks.
