Also, according to the Replay Gain spec, the album gain should be user-
editable, and hence could be different for different tracks.

The spec refers to album and track gain as audiophile and radio gain.  The 
radio gain (or track gain) make every song the same volume.  The audiophile 
gain (or album gain) makes every song the "right" volume for the song, a best 
approximation of which (for automatic tools) is to keeps songs on the same CD 
at the same relative volume.
