Project Description:
I need someone to fix a few things on a wordpress website.

1) The website has 2 main post types, one that displays artist and another one that displays songs and videos (we will call it project). The songs are being played via the Fullwidth audio plugin (http://codecanyon.net/item/fullwidth-audio-player-wordpress-plugin/1321160) and the video with some custom work I did on the site.

They both have their own page, but I'm also displaying some projects on the single artist page. When editing or adding a project, there is currently a dropdown menu in each one of them on which I chose which artist page it should be displayed on. In other word I can link both post type together and display some specific project on an artist page.

It was working well until a few days ago, when I added a new artist. I cannot find this new artist in the dropdown menu of a project and the projects displayed on an old artist page disappeared.

I need to fix this.

2) The Fullwidth audio plugin also customized a bit to fit my needs, but for some reason, I can no longer change the basic settings of the player in the option pannel. All the changes (ex: put the player at the bottom of the page, disable shuffle, change height, etc...) are correctly saved, but aren't applied to the page. I would like to restore that.

3) The custom post type for songs and videos also allows me to include a link that will be displayed below the title. I have 3 post category : Single, Album and Video. When I add a link, it will automatically be displayed with the title "Get the song", unless it is a video in which case it is always written "video".

What I would like to do is change the title of the link depending on the category. If it is a "Single", it will be displayed, "Get the Single". If it is an album, the title should be "Get the album". If it is a Video, it will stay the same as right now, it will be displayed "Video".

4) Each Artist have it's own header with a custom image on top of the usuel header background. There's a little parallax effect with those 2 elements. Currently, I manually change the custom image via CSS. There's a div on top of the usual background on which I change the background-image with the unique post-id css class. I would like to be able to do this automatically by uploading an image via the admin pannel.

Thank you,
