~9000 albums.

I'm not saying it's small but even if you load the whole 16 MB file to
RAM, why does it take up so much space?

My file is 1.9M, that's 16 MB unzipped. In KDE System Guard's process
table, Vmsize 277988, Vmrss 243480. (I double checked with top command
too).

No images, no pixmaps, nothing at all.
