I AM REALLY BAD AT MAKING THIS HARD

It is in fact "Poker Face" by Lady Gaga!  S3L10_Sl33p and Ustaly got both the song and artist, while Ana and Rando both got the song!

Ok maybe this one won't be guessed as quickly-

Difficulty: Hard

Addicted to adrenaline

And always looking for attention

Thought to be so genuine

When she's suddenly met with apprehension

The fighting has begun

And she'd do anything to get ahead

Like using people as ladder rungs

And sweeping eggshells under the bed

OK THIS BETTER BE HARD-
