Artists you liked but completely fell off?

I remember thinking Kid Cudi's debut album was a classic and that he'd be one of the biggest hip-hop stars for years to come. He's barely relevant now though and almost everything he's released since has been below par (although I did kinda like Indicud). He even put out a rock album which was embarrassingly bad.

I also thought Arcade Fire's first few albums were great but just can't listen to them anymore.
