hey! a sonic youth and yo la tengo fan?? woo hoo! hmm.. well I'm a virgin, but I think that albums that could suit the mood might be

adore - Smashing Pumpkins
unplugged in new york - Nirvana (you get the applause every 3-5 minutes )
perhaps...
rated R - queens of the stone age (if you like it rough hehe)

songs that mean something to both people though, for instance, my girlfriend really adores the song *hummer*...(hmm, appropriate name ) by the smashing pumpkins and its emotional and defines points of our relationship yadi yada... we need more posts involiving music everybody!! at last something I can have a substantiated (sp?) opinion on.
