I deal in subtlties, and usually when someone tampers with a lyric by, say, adding a line or changing a word, they usually destroy the subtle, in favor of establishing the obvious. Still, I tend to review the added to or diminished lyric for a week or two in the chance that it might be me that's missing the point. If I fail to reach an agreement with a collaborator, what we do now, is create more than one version of the song in question, and let the people decide. You can't work at any job sucessfully nor play any game and win if you do not have an understanding of the guidelines and or rules of that job or game. Songwriting is no different.
Experience levels contribute to many disagreements.
Experienced writers are usually not too eager to work with writers who, for example, know little about song structure, Inexperienced writers are often still learning about the process when they start that first collaboration, If two inexperienced writers collaborate and know little about the process,then it's likely to be a difficult relationship. One very good way to avoid disagreements is to learn as much about the potential collaborator as you can. See if that person is a good match for your skill level and initiative. Determine what sort of person you will write with and who will avoid. All rights reserved.
