In Amarok 1.4 when you add a song to the collection and play it Amarok automatically generates the .mood file of that song. In version 2 Amarok doesn't generate these files, so I have to generate them manually (very annoying). This is normal or I have something wrong with my Amarok installation? Thanks!

Automatic generation of the files is not yet implemented, so there is nothing wrong with your install.

Ok thanks!
