Undisputably, Definitive Good Songs

[The Devourer Of Worlds]

And J.S. Bach's Jesu Bleibet Meine Freude (Joy of mans desiring). Everybody likes that song.

Nobody knows it by name though, until they hear it in a church or I don't know, in The End of Evangelion...

I guess the same can be said for The 5th in C minor, but then anyone who doesn't know it by name probably isn't worth talking to in the first place.
