There's no doubt about it- Justin Timberlake makes a good album. The songs are fun, and catchy, but there's innuendo in all of them, and over-the-top sexual content in SexyBack. I listen to some of it with my 12-year-old sister, and most of the sexual content goes over her head, but overall, I wouldn't recommend it for anyone under 15.
One look at the title of this CD and you'll know immediately that this is not for anyone under 16. There is over-the-top sexual content on songs like "SexyBack". Although not one song on this album is not about love, there are some safe tracks about normal, everyday teen love like "Summer Love" and "My Love".
