TuneFind is user supported, just like here. The version in the episode had an organ in it, and I haven't been able to find a remix or cover to match it yet. Hope springs, and all that :) .

Well, it's not like the web admin got the episode up...

No, they've buried the music so far under the dialogue I can't even hear the lyrics. It sounds so familiar, though (I know, I say that every time :D ).

Lyrics from the opening song:
She's been waiting
For the Summertime
And now she's saving herself
For another guy
Speak soft, shut it off
They won't do it ever again (? not sure this line)

Does anyone the song blasting from Eli's clock radio when Jim wakes him up?

Has anyone figured out the song at the bicycle shop? Some of the lyrics are:

take a look around you
you've got no place to go
you'd rather die here
than leave all you know
