I used to be a huge fan of DCFC, haven't payed much attention to them in about a year :\ same with Cute Is What We Aim For. I tend to put them together for some reason.
Evanescence&Paramore are really well known, IMO, despite Evanescence being one of my fave bands.
Porcelain And The Tramps however
[lmfao at JUST how much I obsess over them]
