I was visting the Star Trax website that lists the Neptunes projects with different artists and i came across Britneys name with 4 songs, "Boys", "Co-Ed Remix", "Baby Cant U See", and "I'm A Slave 4 U". Does this mean one of their songs didnt make the album or did they have something to do with toxic???? u can check it out for yourself Star Trax Website
