I would include Harrison's "Don't Bother Me" on this list, his first Beatle contribution.

I only showed up at the local theatre to see America.

Any music "movement" is only as good as its songwriting, and there were some GREAT songwriters in grunge. The fact that so many grunge practitioners were self-destructive is what limited the duration of the trend as a whole. Tough for Layne Staley to write new material when he's stoned out of his mind until he dies.
