The other lists speak to me as it is so I want to mention some songs that did not make it into the lists although Lee has a large part in writing all Sonic Youth music... some of these do feature Lee vocals.
I could list many but i will only list a few in case anyone else is interested in making a favorite Lee music even if not officially a Lee song list. : ) it is kind of a messy list, apologies.
Antenna
Silver Rocket / Trilogy / Sprawl+Cross the Breeze
Ghost Bitch / Hallowe'en / Flower
Becuz / The Diamond Sea
Hits of Sunshine / Female Mechanic / Wildflower Soul
Xpressway / Shadow of a Doubt / Marylin Moore
New Hampshire / Peace Attack / Pattern Recognition
Catholic Block / White Cross / PCH / Beauty Lies in the Eye
and....
NYC Ghosts and Flowers / Murray Street just in general needed Lee just as much they needed Jim to be as masterful as they are! Lee's futurism and exploration mixed with O'Rourke's well-honed creative pallete was and still is a once in a lifetime.
