ramones social distoration generation x sex pistols rancid some of the clash . The dammed are good to me more gothic rock. A.L. I agree she's a posure and I would consider regular pop/rock light rock that is. She may have some talent but not a punker just cause she dresses in black and looks kinda dark in style and sounds angry in some songs. Punk is a rage and statement and anarchy & not giving in and just letting loose. Green day is good because their music is catchy sounding but I think they are more alternative rock/pop sounding to soft for true punk but then again I think placing artist sounds in genres is not always good. Being creative is a personal things and all style can be good at times. Not to sound hypocritically but its more like one person likes is not anothers.
