Foo Fighters mainman Dave Grohl has reportedly penned an open letter to Metallica, pleading with them to make sure their new disc is 'kick-ass.' And who could blame him? The one-time Nirvana kitman writes:

"Dear Metallica:

Hey, it's Dave! Remember me? Yeah, I'm the guy that's been listening to your band faithfully since 1983. I bought your first album 'Kill 'Em All' from a mailorder catalog called Under the Rainbow, I think. Actually I can't remember. It was 1983 for Christsakes! But that album changed my life and I've been listening to your albums ever since (even 'St Anger'!).

I can't wait to hear the new s---, and no matter what you guys do I'll always be first one at the shop waiting to hear it. I'm sure you'll come out and blow everybody's f---in' minds, because you're f---in' METALLICA!

Good luck. And don't release it until it's kick-ass.

Yours, Dave Grohl.

P.S. Are you finished recording the drums yet?"

We second that.
