Megan, here is my vision:
It is a member of Sony Music who announced previously that Wish You Were Here would be the last single from the albbum Goodbye Lullaby. The reason is simple, the album sold poorly except in a few countries like Japan for example. So it is normal for her record label, not to support an album, by the creation of music videos costly, if there is no return on investment.
This is the first commercial crash for Avril Lavigne, this happens to all musical artists (Madonna, Britney Spears, Rihanna ...). This does not mean she will stop her career. During the Much Music Awards, she announced that she was already working on his fifth album, just be patient for it, it will be released in due course, probably one or two years minimum.

Sorry if my English is imperfect ... I'm French

people been saying after the black star tour is her leaving tour :/
and are u sure about her fifth ablum?

I don't want to be rude, but what makes you think she is going to leave her music career? Her album was named Goodbye Lullaby because of her HUSBAND not because of her fans or anything.
Avril would never leave her music career after only four albums!

Um, Avril is nowhere near done with her music career. She is releasing her fifth album real soon! Which I hope will be more successful than Goodbye Lullaby and get her some new fans, along with regaining her popularity in the music industry.

Hey I think record labels are yesterdays news anyways... The power of the net is vast and she can do better on her own i think anyways.I think she will become a superstar at least I hope so.Any case she has me as a fan and i will help in anyway I can.

Really like wish u were here....
