I still don't understand why she disappeared from the map here in the United States. I guess when her music & style evolved, we couldn't handle the change here. Not surprising. I find it ironic that she did back up vocals for Britney Spears on "Piece of Me," which = the back up singer being ten times better than the main act. Although that probably happens quite often.
Still can't get enough of her self-entitled album with tracks like "Be Mine!" and "Who's That Girl"...can't wait for the new one to come out!!! If she's fallen off your map, I'd say she is worth giving a second listen.
