“I actually have Aaliyah on a song,” T-Pain told VIBE. “These are vocals people never heard before. They were actually doing an Aaliyah album a few years ago. They told me do two songs and I could pick one to keep.”
But after his release of the mixtape, the song was not featured on the track list.
During a listening event for iboTV, T-Pain justifies his use of auto-tune after he recieved backlash by saying, "auto-tune is more popular than ever now." Then he goes on to say the backlash is a result of Aaliyah's lasting legacy being compared to an "asshole who died and you go to his funeral and say he was the greatest man..."
This video has some of the song he did with posthumous Aaliyah vocals. At the end of the video he is greeted with a room full of WTFs when he talks about the critism surrounding the song and his use of Aaliyah.
