As far as Elvis being "overrated".......aren't they all? I mean really? lol I think one could make that case for anyone if you're not exactly a fan in some way. If I spent the time typing it all out, there's something I could come up with for each of these that is overrated in some way. lol to me it just comes down to who has had the most longevity....the most influence....who had the most impact on the world around them? A lot of different factors....regardless of what I, personally, think about them. Because, like I said before, I wouldn't necessarily call myself a "fan" of a lot of these.
let's face, as has been said before......a big part of this is personal opinion and taste.....as hard as we try to avoid it
