Listen to what you think is right.
Growing out of certain genres or artists is normal, whatever you like listening to that makes you happy.
You can still be "gangsta" and listen to Avril. (I don't even know what gansta means, I just dislike anything rap affiliated most of the time.)
But as said, if you really are not into Avril anymore cause you just don't feel her music is you, it's cool; it's fine. Change is normal and healthy
