Hi. First of all thanks so much for you time reading this and for trying to help.
I search for an Avril Lavigne song in which she reference herself and other songs of their own in the lyrics. I don't remember quite well the melody, but in the lyrics it was something like
"And i hear Avril song on the radio";"Now there's no skater boy";"Now everything is complicated".
Those aren't exact lyrics from the song, they are just the main idea of one section of the song. I remember that the song, in general, was about that she grow up and now everything is different.
Thanks so much for the help.
