"Happy", by Best Coast. In theory there is no reason why I would have any interest in Best Coast. They do nothing I haven't heard before and nothing, again in theory, that I am not by now entirely jaded by.
But enough of the theory. A song like this comes on and it's like somebody has opened a window and in has come a blast of pure, fresh and clean 1989 air. All 1 minute 45 seconds of it. No time for beard stroking when that happens.
Featuring, as too few songs do, the word "cranky".
