Not saying this because of that tweet, but I wouldn't be surprised if her album had hip hop influences BECAUSE ALL HER ALBUMS HAD AT LEAST A LITTLE HIP HOP INFLUENCES.
LG's obvious one is Nobodyz Fool
A few instrumentals have an urban feel mixed with rock, Freak Out being the one that sticks out in my head.
TBDT, self titled track, another obvious one
And the Max Martin instrumentals on GL scream urban. The intro in Smile, the synthetic clapping in WTH, even WYWH's rhythm has a hip hop feel.
She isn't going to abandon her urban influences just as much as she isn't going to abandon rock influences. What I love about her music is that it can only be described as "Avril Lavigne," just as she said all those years ago.
