Which came first: the song title, or the song?
Clearly if it was the latter, I can see why Coyote Kisses landed on the name. Part of me, however, would like to think it was the former: that the LA-based outfit decided to name the song "Sunny Day" before embarking on composition, only to land on something that perfectly captures the vibe.
Either way, it's bubblegum as shit.
