I had to dig to find this and I know the song isn't rap but the verse is. Hell, I don't even know if it counts as a verse. Genius has it listed as an "outro", but Ghostface Killah on Miley Cyrus' song D.R.E.A.M. is ridiculous. It is the last ~20 seconds of the song and what was a pretty alright sort of ethereal pop song suddenly has the music change out of nowhere and Ghostface comes in rapping....just kind of out of nowhere? It almost sounds like a different track got edited on to the end of the song by accident. Except the song is clearly referencing the Wutang song D.R.E.A.M. so clearly it is intentional. Idk.
If we are going to keep it strictly Hip Hop, Soulja Boy fucking ruins Trigger Finger by Lil Wayne. I was re-listening to this album a few weeks ago and while it isn't Wayne's best it has some solid songs on it. This WOULD have been one of them if Wayne hadn't decided to have a fucking Soulja Boy boy feature in 2013.
