Kristin Chenoweth Says 'GoT' Ain't the Only Show in Need of a New Theme

Kristin Chenoweth thinks HBO has more than 1 show that needs a new opening song ... and her choice is timely.

We got Kristin at LAX and asked if she had any other shows besides "Game of Thrones" she wants to redo, like she'd mentioned to Jimmy Kimmel last week. She seems to think "Veep" is due for some vocals ... and then lays it on us.

HBO? Get Kristin's agent on the horn.
