I've always thought that Pink Floyd (esp. during the Roger Waters years of course) put a lot of care in their albums' last tracks. Many times the last track was a summation of the album's theme, and often very moving lyrically, and sometimes musically as well.

Consider "Outside the Wall" for a perfect example.

Or "Two Suns in the Sunset" for one that's as powerful lyrically, but the music helps make it into a song which could stand on its own.
