Request: Song help!

(Texas)

In "Felicity" Season 2, episode 5, about 39:00 in, a song plays (sung by a girl) that goes "I aim to please you, what's best for you must be best for me, don't shake your head, i'll do better, don't walk away, i'll try harder."

It is not from the show's original soundtrack, but rather, was added when the show was added to Netflix and put on DVD. I realllly want to find the song, so I'd appreciate any leads :)

Thanks!
