I've also got a mashup of Lady Gaga's "Telephone" and Metallica's "Enter Sandman" stuck in my head

I can't remember if it's a real song or if I'm making it up

......that sounds like an awesome mashup

Well, it sounds pretty good in my head.

apparently it is a real thing!

/googled it

Oh, good, it's not just me. /goes to find it
