When I had a group we had discussions about everyone's goals. This exposed (and sometimes resolved) all the musical issues, right up front.
We had to work with the things we liked.
I was right up front about saying that if someone hates a song, then we wouldn't do it.
What was left was what we did - still plenty of material.
But for those who didn't like enough of what the others liked, well, we looked for replacements.
When you run out of replacements, the band is dead.
And maybe it's time to change what we like (!!!!), or, more realistically, find the place where folks who love YOUR style of music hang out.
Make new contacts, and try to start fresh there.
