In a new interview with Tori Kravitz of Knotfest, KREATOR frontman Mille Petrozza was asked to name his "top five favorite heavy tracks".

He replied: "I would go for something by JUDAS PRIEST, for example 'Electric Eye'.

IRON MAIDEN, I would choose the song 'Killers'.

Something by CELTIC FROST, 'Circle Of The Tyrants'.

It's all old school so far.

Maybe something really heavy, like something by METALLICA.

I would have to put 'Blackened' by METALLICA.

That's one of my favorite riffs ever.", He continued: "The ultimate heavy metal song must have been something by...

It's so cliché, but it probably needs to be something by BLACK SABBATH.

I would go for 'Symptom Of The Universe'.

It's not the obvious choice — everybody would go, like, 'Paranoid' or whatever — but I think 'Symptom Of The Universe' has this amazing riff.", Mille added: "It's almost impossible to [choose only five songs].

I love all kinds of heavy metal, and I love all kinds...

I like the newer stuff.

I like the older stuff.

But I had to pick five, and obviously those are classic songs."
