Naw. Undercooked? The song does more in a minute and a half than several songs do in 7, 8, 9+, and any more would probably be dragging it out. What else is there to even add? "One by one, the stars are still there, the sky herp herp something qabout koala bears gimmie gimmie ass treatment"
I'm not saying the song has to be some 5 minute epic where the "one by one" verse has to appear eight times. I just think it's undercooked in the sense that it's just a stellar verse and a chorus repeated a couple of times with no bridge/proper outro.
I love and am completely satisfied with Had to Phone Ya even though it's short but it's because there's a few more twists and turns in the package. If Brian had just repeated the first verse after "just a dial away" and faded out there instead of going into the bridge and outro, I'd feel shortchanged in a way that I do here.
