Former 'N Sync singer Jc Chasez has lavished praise on Justin Timberlake for being "brave" enough to experiment with sound. Chasez was so impressed by his former bandmate's risque new album FUTURESEX/LOVESOUNDS he begged Timberlake to co-write and co-produce three songs for his own disc. Chasez tells MTV, "He has a phenomenal record coming out. Obviously, he's one of my best friends. But (new single) SEXYBACK is a brand-new sound for him, and it's opened up a lot of minds. "The safe route would have been to make another record like the last one, because it was so successful. But I like the fact that he said, 'No. I'm going to be artistic. I am going to change my sound,' because that's what he was inspired to do."
