^ She really capitalized off the teen-pop sound. She should have been smart like Britney (or her handlers) and kept pushing out albums. Britney's debut scanned 10.6 million, then even "Oops!" did 9.2 million a year later in 2000. "Britney" (late 2001) only sold a couple hundred thousand more than "Stripped". Christina probably could have had another 5+ million seller if she followed the same template of her debut in 2000.
