Drummers who sound like a drum machine. Which in my expirence is most of them.

You can make music with a drum, but mostly they are used just to force the rest of the band to stay on beat (you kinda wonder about the rest of the band) There is a difference between playing the right notes, and making music. The latter doesn't nessicarly involve the right notes! I'd rather hear a real musician play flat, then hear anyone play exactly the right notes as written without feeling. Drum machines have no feeling, and most drummers immitate the lack of feeling.
