I will say some bands def get called sellouts prematurely, and its true just cause you get on mtv doesnt mean your a sell out.
I was jking not all the bands you like jp are sell outs, but good charllotte isnt a sell out its just that thier music has gotten worse each albumn. I used to like them.
That last song they released was a cheesy 80s remake with goth piano.
And what band wears thier own tshirts and clothing line real lame real lame.
You become a sellout when you base your music on a marketing startegy and thats when it becomes about the money and not the music anymore, ie you are a cooperate sellout.
If good charlotte is a sellout i dont know but they are suspect.
