DNJ, if someone tells me that my voice is out of tune, and I say, "Hey, you're infringing on my original intent as a songwriter," that's pretty stupid.
If several people in different forums say that your hook is great, but the other lyrics aren't very professional, should I tell them, "Hey, if I change anything, that's messing with my original perception." That's pretty dumb too.
Because of some constructive criticism, I tuned up my vocals, and I reexamined a song, and wrote verses that were more cohesive with the theme of the hook.
I'm intelligent enough to take any critique with a grain of salt. But I'm also intelligent enough to listen to people and see if what they says reverberates with what others say and what my inner voice says.
