Record Labels

I'm going to try to contact some record labels by email and ask them if they have a process for creating a successful album cover.

Here are the questions I am going to ask;

Does the record label have any choice in deciding album covers for artists/bands?
If yes;
- Do you have a specific team for it?
- Do the artist/band sit down with the team and decide?
- Are several covers drawn up/made then decided on?
- Do different people do different jobs, e.g Title name, cover colours, back design, lyric book design(if there is one)?

I'm going to try to contact these labels first (pop/rock genre)
