When I try to play a song with the latest upicek branch I get an error like this:
$ python elisa-core/elisa.py temp.conf

It seems that the code of the tutorial is not up to date with latest changes to the models.
This is probably not specific to upicek and should be fixed in the 0.5 branch.
In any case elisa.plugins. tutorials. amazon. metadata: AmazonCovers should be removed from upicek's default configuration.
