"Bright" is one of the few bits of music I highly enjoy without quite being able to analyze and categorize.
While not particularly expressive of lasting commitment, the lyrics have a sweet innocence about them... a simplicity and sincerity which, compared with the garbage of far too many other songs, is most refreshing.
This song has a cool breezy vibe to it, but of a sort that I find difficult to assign to a particular season. The softness of spring and the carefree attitude of summer are most clearly felt, yet the camaraderie of fall and the piercing precision of winter are represented as well.
At any rate... I like this song muchly.
