For years, Christina Aguilera had tried to prevent the release of “Just Be Free,” a collection of recordings Aguilera made when she was 14 and 15 years old. The diva-in-training, now 20, recently settled with Warlock Records on the condition that the album would contain a message that says in part: “I made the recordings as a possible stepping stone to a career in music, which is my ultimate passion. They were made just so that I could get my foot in the door of the music business. I did not intend that the recordings would be widely released, especially after I signed with a major record label.
