Rap mogul Jermaine Dupri has lavished praise on partner Janet Jackson's forthcoming album for continuing to set the standard for her female contemporaries to follow. Dupri, who plans to wed the singer in September (06), insists new record 20 YEARS OLD will leave other pop stars lagging behind. Speaking at a press presentation for the album on Monday (24JUL06), producer Dupri said, "Only Janet records sound like her. I always look and think, 'Where's Beyonce going to be in 20 years?' It's hard for me to visualise. I don't put them on the same plane. "Janet doesn't go for the same typical cars and street videos. She was the reason we started to watch TV. She's back to her full capacity and blowing it out to the level. "Artists just need to make good music. I said to Janet, 'All you got to do is sing.' "BRITNEY and CHRISTINA (AGUILERA) are all copycats of one person."
