Except Iggy ain't in my sig "to showcase and brag about" so you're literally just spewing fallacies to no avail.
Iggy's in my sig because I bop to a couple of her songs at the moment. That's literally it. I change my sig like a girl changes clothes (buy Hot N Cold on iTunes), this has been known.

She still SUCKS and you should be ashamed to publicly claim her? Like 100x more than Gaga.
I basically like every artist anyway so dragging my taste is kinda self-depreciative in a way as chances are I like your fave. The only artist I've ever really claimed to dislike is Mariah Carey, and even then I plan on listening to her #1 to Infinity album or whatever it's called because I want to give her a fair go before I completely write her off.
Song of the summer. Dr Luke milks Roar for all it's worth and it still sounds fresh every time. Katy kinda is the standard (for him and his productions at least).
