For some strange reason I cannot find your answer on the question where you said Amy Winehouse and Adele are similar. So weird. I went to click on it and the page reads everyone else's answer but yours. ???
So, what I was going to say is that I see no resemblance to Amy and Adele at all. They don't even sound the same.
(I know that wasn't important, but I am just wondering why that happened)
I don't think that at all. It is the same as when I think someone looks like another person. You may not see what I mean. I am sure you are hearing tonal qualities in their voices I never paid much heed to.
I will now look for that when I hear them. They both possess those deep, throaty sounds, so you may be referring to that.
Who knows? Here is Amy and I just started to listen and I kind of see what you mean now. I can certainly tell them apart and would never confuse the two, but they both have those strong, throaty voices and both are from England, so they pronounce things similarly.
