Top Ten Songs That Changed a Band's Style

As in the first song /single from an album that changed a band's style. NOT NECESSARILY IN ORDER OF FAVOURITES BUT CONSIDERS TIME AND HOW MUCH CHANGED.
The Top Ten
1 What I've Done - Linkin Park

BRILLIANT, CLASSIC SONG. Changed their style from their previous Nu metal + hip hop sound to one of rock.

2 Happy Song - Bring Me the Horizon

Changed their style considerably.

3 The Catalyst - Linkin Park

Changed their style again on A Thousand Suns, this time MASSIVELY.

4 So Cold - Breaking Benjamin

My favourite song on this list at the time of me writing this, and one of my all time favourite songs. We Are Not Alone turned their style more serious and darker from Saturate.

5 No Way Out - Bullet for My Valentine

Massive return to sound... The list doesn't necessarily mean a brand new sound, it can mean going back to an old one that breaks their current norm. EPIC SONG.

6 I Won't Give In - Asking Alexandria
7 Duty - Dawn of Justice
8 Get Up! - Korn
