JC Chasez has just finished recording his sophomore album, due in the first quarter of 2007 via Jive. The as-yet-untitled effort comes three years after his solo debut, "Schizophrenic," and more than five since 'N Sync's last album, "Celebrity." The 30-year-old wrote or co-wrote all of the songs on the album and has enjoyed the freedom of "being myself."

"When you're in the writing process for yourself, solo, there's no compromise," Chasez tells Billboard.com. "Before, you had four other guys you've got to pass [the song] by, and everybody has to decide based on the image of the group. It's not that it was a problem -- it was an act of respect. But when you're [writing solo], everything is essentially you."

Chasez describes the set as an amalgamation of the many genres he loves, with an emphasis on melodic pop elements. "It establishes a sound that is specific to me, a mash of all things," he says. "I hope it'll be fresh for radio and listeners. In '97 and '98, pop ruled. But now hip-hop is the phenomenon and top 40 radio doesn't play pop records anymore."

Chasez recruited celebrity producers like Timbaland, Dallas Austin and Jimmy Harry to co-write and co-engineer the tracks. The first single from the effort, "Until Yesterday," will be released to radio Oct. 20 but can be samples from Chasez's Web site. The track was co-written by Chasez's longtime friend and former bandmate Justin Timberlake. The pair has written several other songs together, although Chasez is unsure which ones will be included on the record.

"We always want each other to do well," he says. "Each of our successes feeds the others', in my opinion -- it feeds the fire. Just because one of us does well, it doesn't mean there's no room for the other to do well."

The two seemingly went head-to-head for headlines in 2004; Timberlake's Janet Jackson/Super Bowl snafu was well underway as Chasez released "Schizophrenic," and some believe an invitation to perform at the NFL's Pro Bowl was rescinded because of the incident.

Despite a heavy promotional effort, the record only peaked at No. 17 on The Billboard 200. "That's just life, man. Sometimes its a beautiful day, sometimes it rains," he says. "I was very proud of that record and took a lot of chances artistically. It was just a matter of wrong place, wrong time."

Along those lines, Chasez says 'N Sync is unlikely to reform anytime soon. "We had a great time, but we're in different places in our minds now," he says. "It ran its course. It's like, ok, we went to high school, and now it's over."
