An artist's name is missing from my iPhone, how do I get it to show up?

The artist is not showing up on the 'Artist' list on my iPhone, yet their music is on there and they're showing up on the 'Artist' list on my iTunes account… How can I get the artist back onto the 'Artist' list on my iPhone? I've tried syncing it with no success. I don't want to have to delete the entire music library and replace it for such a small detail… But if that's what I have to do, then I'm prepared to do it.

Go into iTunes and right click the song>Get info>Info tab>Add the artist manually
