Lots of that today... we've been writing this song for a while now, and everyone knew their parts, but the drummer decided not to practice until today.
The vocalist couldn't write anything to match us because he's been so dead set on a different style recently.
The guitarist can't grasp 3/4 time and was noodling constantly.
The drummer would get off topic on something else then tell everyone else to get on track.
The one thing that really got under my skin is that I had a song written and everyone in the band is wanting to change everything about it, going from heavy metal (my intention) to some screamo crap...
