Well, I am a singer and one of the reasons I usually have arguments, is that many musicians I've met want to be rockstars and they are too loud, or they try to do things without considering the vocalist. We can be as idealistic as we want about it, but except for one or two bands in the industry, in most bands either the vocalist alone, or the vocalist and one more musician are the leaders, and the rest need to understand the person who is the face of the band, and the person getting along with the audience has certain needs, and you can't change your vocal chords as a guitar player changes the strings of his guitar, so they need to follow you, and not the other way round. This is especially important when musicians are being too loud, like I said, or when they want to play a very aggressive, loud tune, and then play a romantic one, and they expect your vocal chords to magically relax, or they expect you to sing fot 5 hours in a row in a rehearsal without getting tired just because they didn't study their songs beforehand and they need to repeat a part of a song again and again. It sucks and it's not the type of environment I enjoy. I also hate it when musicans expect singers to magically be ready to sing without warming up.
