Me likes the eargasm retroplasm...
I think "sounds preferable to me" is the only accurate statement that doesn't involve an unresolvable spiral of interdependent definitions (What is 'more musical'? Sounds better! What is 'sounds better'? More musical... Etc.) that only ends in a fight.
Drawing an analogy to some other preference -- e.g., some folks like blue and some folks like red, but I like blue and this sounds "blue" -- might be helpful.
Can we further " Reductio ad Absurdum " ....
How about -
"I like it"
By the way, I can't believe you like the sound of blue....
