Aguilera also recorded a cover of All-4-One's song "I Turn to You", written by Diane Warren who also wrote "Somebody's Somebody". Carl Sturken and Evan Rogers (who would eventually break into the scene as the producers who launched Rihanna's career) wrote and produced two tracks ("Love for All Seasons" and "Love Will Find a Way") Travon Potts & Brock Walsh wrote and produced "Blessed", while the then up-and-coming Robin Thicke co-wrote and co-produced "When You Put Your Hands on Me". Franne Golde (who previously worked with Whitney Houston) also wrote a song for Aguilera titled "So Emotional" which was originally written for Selena's album, but unfortunately she died at the age of 23. The track's producer, Ron Harris, revealed that Aguilera in-between recordings "was only listening to Mariah Carey and Brandy, putting on her walk man and practicing their riffs and runs, before she did her ad-libs. At the final stages, producer and songwriter David Frank presented a song called "Genie in a Bottle", which Aguilera almost didn't record, "because there were a lot of other artists out there that were after this song, so we had to fight a little bit to get it," she claimed. With Heather Holley, Aguilera also co-wrote along with producers Heather Holley and Rob Hoffman a track called "I Will Be", which she said was inspired by Mariah Carey's "Vanishing". The duo also wrote and produced the album's final track "Obvious", and "I Come Undone", which was ultimately not officially released.
