I am not Solomon, so I have to work harder for an answer. :-)
When I started leading the morning minyan, I did the service exactly as it was taught to me -- Hebrew here, English there, this melody, and so on. I have made a very few changes, gradually; after noticing that different people do in fact do it a little differently, I figured I could get away with that if I didn't jolt people too much. I made changes in the things I most care about.
Over time, I've learned, everyone else who leads this service has drifted away from one particular melody. Some people have asked me to kill it too. The rabbi, who is mara d'atra so may insist but knows the minyan was there before he was so he won't, hates it and said he would be delighted if I chose to get rid of it. I, personally, do not care; it would be hard to find a part of the service that I'm more neutral about. So for the last couple weeks I dropped it, just chanting that passage instead.
Naturally, there is one long-time, regular member who loves singing it and thinks people went behind his back to lobby me. He begged me to put it back. I did this morning, making a slight change to address what I perceive to be the rabbi's main complaint. (I haven't talked with the rabbi yet, so I don't know if that was effective.) Sigh. I wish I actually cared about this particular issue; then I could assert a position and go.
I might look for a different melody and see how that goes. I don't know any that fit all the criteria right now, but I haven't done any real work on this yet.
