I write a song with a tempo in mind, and the drummer speeds it up. He speeds it up alot. He thinks fast = good and that's all there is to it. Problem is, he speeds it up to the point where I actually can't play it the way I wrote it. I've plainly told him "sweet mother of holy crap, that was ridiculously fast, I SIMPLY CANNOT PLAY IT THAT FAST" and he's like "okay ill slow it down next time" and he thinks he's slowed it down but it's JUST AS FAST. Any advice?
