I think her album Damita Jo is very underrated, in my opinion it's her best album of the 00's. I Want You, R&B Junkie, Island Life, All Night (Don't Stop), Strawberry Bounce, Just A Little While are all great songs, and I have no doubt, had the Superbowl not taken place they all would have been hits if released, not only did it have an effect on Janet's image (being blacklisted by MTV, no airplay etc.) but I think it affected Janet's confidence a little, having said that, with it being blacklisted it still managed to achieve 2 number ones in the US and a number 2 album against probably the biggest artist out at the time (Usher). Plus Janet looked stunning during that time, its hard to believe she was almost 40!
Here's my favourite performances of the Damita Jo era:
