Yeah... I think they have very different voices. However, I get that any female fronted band from now until Paramore is forgotten about will be compared to Paramore even without the similarities. Kinda annoying.
I wrote a review for a band called Everlyn back when I had just started reviewing records, and I didn't mention Paramore once because there were no similarities. At times I think that this girl sounds exactly like Hayley. Not that she's a ripoff or anything, because she has her own style, but I think there are definitely similarities.
