It's played during the ending credits, after the Incubus song. It's kind of acoustic and folksy and contains the lines "it's time to go" and "who could've asked for more?" Google searching for songs with these lines isn't helping. It think it must have come out in 2002 or around then, because MTV tended to use contemperary music in Daria, but it sounds older- kind of like America, or a band from that era. Does anyone know what song I'm talking about, or who it's by? I know this is very vague, but any help in finding this song is greatly appreciated.
EDIT: Found the song. It's "It's Time to Go" by Supergrass.
