New killer concept - the Rockstar

At a glance:

• 115% movement speed (alt. 125-135% with add-ons listed below)
• Not a licensed one, supposedly his name is Andrew
• Tall height
• 32m Terror Radius

It's basically an M1 killer with a unique power called Power Chord, allowing him to deafen survivors and often forcing them to hide in lockers to help their deafness go off.

Power Chord:

Press the power button to activate Power Chord when the power gauge is full.

• Power Chord is active for 10 seconds after activating, during which a heavy metal song is being performed. The power needs 20 seconds to be refilled and able to be used again.
• When Power Chord is active, Survivors within 48 metres of the Rockstar will accumulate deafness. If the Survivor remains affected by the power for 10 seconds, they gain Deafness status effect and are forced to scream, revealing their position to the Rockstar.
• Survivors passively recover from Deafness within 120 seconds. This process can be accelerated by hiding in Lockers; Deafened recovery speed in Lockers is increased by 100%.

His perks give him more map control and allow him to stay hidden from detection tools to some extent:

Smell of Petrol

Your enhanced senses in the Entity’s world reward you for wasted efforts of your potential preys.

When a Survivor fails a repair skill check, their Aura is revealed to you for 4 seconds.

After hooking a Survivor, the closest Generator to you being repaired by Survivors is highlighted in yellow for 8/12/16 seconds. 

Through the Barriers

There is nothing stopping you and you know that.

Pallets vaulted 3 times during the same chase are automatically broken by the Entity.

When you break a pallet, there’s a 30/40/50% chance that another random pallet within 36 metres of range will be automatically broken as well.

Sounds of Suffering

You have developed a few rudimentary methods to deform marks of your presence.

Hit Survivors perceive the terror radius and red stain as though you were right behind them for 8/12/16 seconds.

Your Aura cannot be revealed and detection Perks cannot be used towards you outside a 40 metres of range.

Descriptions are questionable, a few Metallica references included

According to the "heavy metal song" performed while the power is active, @Peanits would there be any copyright issues if using an already created metal song was needed?
