How many songs did Avril Lavigne write?

As of my most recent knowledge update in September 2021, Avril Lavigne had written or co-written over 200 songs.

Since then, she may have written more songs for her 2022 album "Love Sux" and other projects, so the total count could be higher. You may want to check Avril Lavigne's official website or other reputable sources for more up-to-date information on the number of songs she has written.
