I have been searching and searching for the song in the end of "Time will tell" in season 4 where Felicity and Noel decide to be together. Can anyone help me?

The following are the songs featured in that episode. Not sure which one answers your question.

Tell Yourself by Natalie Merchant
Backwards World by Josh Clayton-Felt
Consent by The Devlins
St Clare by Susan Vega

Hope one of these is it. Try Youtube for each one and check them out.

I have been looking for this song for so long too!! Those songs aren't the songs from the dvd but when it aired on TV. Does anyone know this song? I've looked and nobody could answer
