I know there's a new single to be released of hers today / tomorrow for buying from stores (as opposed to online downloads for a week already IIRC). I don't know of an album. Find out in a week if Britney's single has been hindered by her antics.
I don't follow Britney's music, only the odd track is listenable, much like all of today's music.
I'm kinda interested what the buzz is over there concerning Robert Plant's new album.
