I can't at HIMH being "(feat. Justin Timberlake)" and yet all he says is "you got a hole in your head, you got a hole in your head, girl". I agree, he needs to have verses with Rihanna, but his work as a producer is fantastic. His productions + Rihanna =
I thought he produced LGT, and "Rehab"... but Wikipedia says that he only wrote"Rehab". Is Wikipedia lying? Or did JT not produce those songs?
I'm 100% sure that he didn't only write but produce "Rehab" because he also produced a song that has similar drums, listen:
i know i'm gonna get hate.
But i just could never get into HIMH. it's a good song, but i'm glad it didn't make the standard edition.
Rihanna has attitude, the beat is fierce, and the JT cameo just tops off the song. This song is just fun, and sassy. It's also really fun to sing. It should have made the standard edition in place of "Photographs".

The production is basically the same.
