it's useless to complain when someone says "this reminds me of WHOEVER". if they're saying, it's because it rings a bell on their experience with music.
it's unfair to say "he's copying bob dylan" or "bob dylan rip off", but that it REMINDS people of bob dylan, there's no doubt.
it's normal to say that. when i just meet someone, they always remind me of some actor or someone i know. after sometime, that similarity is almost gone (some cases are exceptions), since you know that person much better. it's a common mechanism in the human brain, you can only relate to what you know.
i have a friend that always DISAGREES when I say someone looks like someone. it's very annoying. if I'm saying, it's because it came to my brain, somehow. no fuss to be made about it.
