Firstly, I would like to state that I have been a fan of Avril Lavigne's for 8 years and a Paramore fan for 6 years.
It is extremely stupid and immature to compare Avril (solo artist) to Hayley (lead singer for band). They make different music and sing differently.
Avril's voice is most compatible for pop music. When she sings pop songs (What the Hell) her voice is strong...when she tries to sing rock songs (Losing Grip) her voice completely falls apart.
Hayley's voice is most compatible to rock songs. Hayley doesn't try to 'pop out' she rocks out. Avril needs to stop trying to rock out cuz it just doesn't suit her.
In my opinon Hayley has the better and stronger voice. She has always been a great live singer and is very consistant. Avril's live performances were horrible until she realized that her voice range was more soprano than alto. Avril is still growing as a singer and has imporved and gotten great live performances out of her growth. Same as Hayley.
When it comes down to the point, Avril and Hayley are different singers. They use a different method to sing, have different voice ranges, sing different music, and are different ages (which does make a difference) They both are great singers.
But my vote goes to Hayley.
Now let's get back on topic!! This thread is about AVRIL LAVIGNE! not hayley williams, or who has the better voice.
I personally really like Avril's new song 'What the Hell' I'm really excited that she's back and can't wait to hear the new album!! I'm hoping it's going to have a theme/tone similar to UMS. I mean she did say that WTH is the most pop track on the new album.
