First off, this is my opinion and you don't have to agree with it. If you don't agree with it, you don't have to read.
So, a lot of people say that Agnetha is "ABBA's Icon" which doesn't make sense. Maybe Agnetha stands out the most of the four. She's the only one with blonde hair (The other three are BRUNETTES... Well, Frida was a brunette once upon a time. Take that, people who think that Bjorn and Benny are blondes. o.O). But she isn't ABBA's icon. ABBA is A B B A - Agnetha, Bjorn, Benny, and Anni-Frid. If anything, they're all "ABBA's Icon". So all this talk about "ABBA's Icon" is complete nonsense.
I just felt like letting off some steam. :P
