I've honestly never gotten why people compare XTC and Talking Heads. Especially XTC's later stuff (which they're more famous for I'd say) isn't anything like any of Talking Heads' stuff.
Probably because they are both grouped up as new-wave/post-punk
I can't really think of any similar XTC and Talking Heads songs, though they might have something comparable to "The Big Country"
