Drake Fans Outraged As Rapper Credits R Kelly on ‘TSU’ Drake has a sample on Certified Lover Boy that has set Twitter ablaze The song in question is TSU. When you look at the writing credits you see Justin Timberlake, Timbaland and R.Kelly. All everyone saw was the name R.Kelly and Twitter exploded. Let’s break it down how we got here. TSU samples an NSYNC song (Justin’s former group) that was co-written by R.Kelly. TSU also samples Until The End of Time which was the work of Justin and Timbaland. In the music business, if you do not properly credit a song a future lawsuit could be astronomical especially when you are someone as big as Drake. Was Drake wrong for still using the song that included an R.Kelly sample?
