For Aggie's current fear:
I want to say: Elastica, "Never Here". But Aggie doesn't seem like a fan of choppy jangly rawr two minute obsession. That's more my taste than hers.
Slower and more melodic: Fleetwood Mac, "Over My Head".
Or if Penny really does start remaking her like Judy Barton from Kansas ("Vertigo"), Pat Benatar, "Heartbreaker".
Something from Melissa Etheridge about being brave and crying and devil take the hindmost and you're going to crash over me ... I can't quite find what I'm looking for. Part "Come to My Window", part "An Unusual Kiss". Meh, again, not really Aggie.
From the guys: Bruce Springsteen, "Tunnel of Love".
"Then the lights go out and it's just the three of us / You and me and all that stuff we're so scared of"
And finally, from Sarah McLachlan, "Fumbling Towards Ecstasy".
(My musical tastes are probably the most mainstream thing about me)
"The fair Ophelia! -- Nymph, in thy orisons be all my sins remembered."
