Avril Lavigne

After Avril Lavigne released hits like "Girlfriend," "Sk8r Boi," and "What the Hell," her career kind of plateaued. She hasn't released much impressive music lately, and the hype around punk bands goes up and down. She's also known to be a terrible live performer, so there's that.  

Bono

No one can seem to forgive Bono after U2 mysteriouly downloaded one of their albums into every Apple user's iTunes library. Also — U2 kinda sucks. Sure, Bono is a very philanthropic guy, but his performances just aren't impressive anymore.
