It's so hard to rank the bonus tracks because how to evaluate?

Most easily could've replaced an album track? Most powerful emotionally? Lyrics? Vocals? Let me go...
Can't Let Go (better than multiple album tracks, super emotional, one of her best studio vocals ever)
I Found A Boy (absolutely devastating lyrically, the true transition song from 19 to 21)
Now and Then (kinda like a baby CLG with the vocal, the only song that always makes me cry)
Why Do You Love Me (cheesy af but one of the biggest bops she's ever made)
Painting Pictures (it just sounds really cool, more alt than she's gone anywhere else)
Lay Me Down (meh)
