You'll Have A "Nightmare" On May 18th. Hear A Clip Of The Song Now!

This post on Amazon would suggest Avenged Sevenfold’s brand new single “Nightmare” will be released on May 18th. The song apparently runs 6 minutes and 16 seconds. You can preview the song here. The preview has now been taken down, I hope you guys got to enjoy it while it was up!  I won’t allow links to the preview in comments because it was taken down for a reason. Hope you guys understand!

Enjoy the single cover art below:

Big thanks to Alec for sending this in!
