These two are my lowest scores from her debut, so these are good eliminations.
With its interesting production and great verses, "Do What U Do" is good and should've stayed a bit longer, but it's one of the weakest on "Can't Take Me Home". I thought it was one of the apparent songs to have a low highest score, but
@Music Is Life gave it a 10 (and, oddly, didn't write any commentary).
"Let Me Let You Know", as already pointed out, has some amazing vocals, but that could be said about each and every song she's released. Being so bland and boring, it remains one of the weakest songs in her discography. The main thing that makes it distinctive is the reappearing male vocals, like it has already been mentioned.
However, it's not the song that I would expect to get an 8 as the highest score.
And
@Lost Boy, I didn't know that Robin Thicke co-write "Let Me Let You Know". That fact somehow passes me by. I know that he's written "When You Put Your Hands on Me" for Christina Aguilera around the same time, which is one of my very favorite songs from her debut, let me listen to it again.
After this, we should leave her debut alone for a while (except maybe for the title track), but that surely won't happen.
