By 2002, boy bands were on the decline. It became common knowledge that Justin Timberlake, and probably JC Chasez, would go solo. Timberlake was the first of the two to release an album, Justified. The lead single was "The Way I Do", but the best song off the album, for me, was "Rock Your Body".
What can I say, I love upbeat, dance tunes. The song actually had tough competition this year - "Crazy in Love" by Beyonce, which was pretty much the same formula. It was a tough choice. But, in the end I went with the Timberlake song.
As for the first albums between Timberlake and Chasez, Chasez's is probably better even though he uses many song styles. The only problem is that the songs which were better were never released.
