The worst song is 1+1.
She sounds like a hyena howling into a fan on the song. ''I dont know much about algibuh, but 1+1 is twooooooooo"
Second worst song is Run the World (Girls). Sounds like something Willow Smith should have sung
I Was Here is actually pretty critically panned because it's a terrible song. Anyone can tell this by listening to how basic the lyrics are, especially after the trio of epic ballads (particularly the flawless I Care) that start the album.
