I'm a fan (and you should be too) because... when i heard for the first time 'Complicated''
i liked it very much. After that , i started to search about the person who was singing the song and i found the person. It was Avril (LOL). Then i started to search more information about Avril. Since that year I started to buy all her albums and I knew she will be my favorite singer.
(I'm sorry about my English. I'm not a very good speaker )
