An unofficial instrumental version of "You're Smiling (But I Don't Believe You)" by Margaret Glaspy.

Please note that the "bluriness" and dips in volume are baked into the track.

In a lot of songs, when the singers get louder, they make the intrumental quieter to avoid clipping or bad mixing. This means the audio file has less information dedicated to the instrumental in these parts. It can't be cleaned up any better. It is simply a limitation of our current technology.
