The Wombat File Is Yours to Keep

The unquestionably correct list, in ascending order of excellence:

10. Elbow Room. The fact that the ideological-historical lesson imparted is now so shame-making that one can't believe this one was made in does not, completely, detract from the sheer goofy catchiness of the song.
9. Conjunction Junction. This would rank, I think, higher if anyone could remember any part of this other than the chorus. But it's a hell of a chorus, and it will get you there, if you're very careful.
8. Ready or Not. Invaluable, right up there with that song that teaches you to spell "Mississippi."
7. I'm Just a Bill. A counterexample to most of these -- better as a memorable peice of filmic pedagogy than as a song, actually. Not that it's terrible work as a song.
6. I Got Six. Not only possessed of a powerful groove, but it ups the math-educative ante over many of the other songs with its elegant lesson concerning the hungry men in the restaurant.
5. Rufus Xavier Sasparilla. An unsatisfying cartoon, but a great and surprisingly moving piece of comic songwriting.
4. Figure Eight. Blossom Dearie and that haunting cello. Also: "Now it's time to get off on your new math tricks."
3. Lucky Seven Sampson. Although "Figure Eight" is almost certainly more memorable as a film, this one is just so delightful as a song that I think it edges the other out.
2. The Preamble. In the alternate America of my dreams, this is what we stand and sing before baseball games.
1. Lolly, Lolly, Lolly. Has it all, punctuated by that gleefully soulful piano-driven workout at the end: "CONDITION! REASON!"

You may post your alternate rankings in the comments, although they are wrong.
