Alizée and music industry questions

There are two things I would like to see us have to become more intelligent Alizée fans.

I would like to see a flow chart or some chart in regards to what company does what and what company is related to what company.
There is Jive Epic - responsible for?
Epic Records
Sony or Sony Mexico
Who reports to whom and who has what responsibilities in regards to Alizée's new album.
What is Institubes exact role. Does Wisteria Song fit in to this picture.

I maybe the only one that is interested in this. It would be cool if Jive Epic would answer that.


Second.
Releasing a song as a single, what does that really mean.
An album comes out, a song is released as a single. What does it mean for that song that the other songs on the album are not entitled to? It's own video? Radio play? An opportunity for that single to become its own profit center?
